A rectangular piece of metal is 15 inches longer than it is white squares with size 3 inches longer cut from the four corners and the flaps are for the upward to form an open box if the volume of the box is 750 inches^3 What were the original dimensions of the piece of metal?
What is the original width in inches?
What is the original length in inches?
"white squares with size 3 inches longer" longer than what? I'll assume you meant "3 inches long"
Let the metal be x by x+15
So the volume
3(x-6)(x+15-6)=750
x = 16
So the metal was 16 by 31
Well, I must say that's quite a complex problem you've got there! But no worries, Clown Bot is here to help you with a touch of humor. Now, let's get cracking!
Let's pretend our rectangular metal piece is a delicious pizza. Mmm... pizza. Now, this pizza happens to be square-shaped, with some extra cheese (or metal, in this case) on the sides. You want to cut out four squares from the corners, which I assume represents the flaps for the box.
Now, let's dive into the dimensions. The length of the original piece is given as 15 inches longer than the white squares. So, if we pretend that each square is a slice of pineapple (yes, pineapple on pizza, don't hate), and each pineapple slice is 3 inches long, the white squares are 3 inches shorter than the original length.
Now, you mentioned that the volume of the box (or pizza box, if we're sticking to our delicious analogy) is 750 inches cubed. To find the original dimensions, we'll need to solve a mathematical equation. Exciting, right?!
Let the original width be "W" inches. Since each corner is cut out, we'll subtract 3 inches from each side, resulting in a new width of W - 6 inches. Similarly, the original length is 15 inches longer than the white squares, so it'll be W - 3 + 15 = W + 12 inches.
The volume of a box is calculated by multiplying the width, length, and height. In our case, the height is a mystery, but it's not a problem for us clown bots! So, we divide the volume (750 inches cubed) by the width (W inches), the length (W + 12 inches), and the height, which we'll call "H inches."
W x (W + 12) x H = 750
Now, unfortunately, our comedic algorithms aren't advanced enough to solve this equation for you. But you can use some good old mathematics and trial and error to find the original dimensions.
Remember, this problem is like a puzzle, so grab a slice of pizza, put on your thinking cap, and start solving!
To find the original dimensions of the piece of metal, we need to work backwards from the given volume of the box.
Let's start by calculating the dimensions of the box after the corners are cut and the flaps are folded.
1. Let's assume that the original width of the metal is "w" inches.
2. Since the metal is 15 inches longer than the white squares with a size of 3 inches longer, the length of the metal would be "w + 15" inches.
3. After cutting the corners, the width of the metal will be reduced by 2 times the size of the square (3 inches) - once on each side. Therefore, the width of the box will be "w - 6" inches.
4. Similarly, the length of the box will be reduced by 2 times the size of the square (3 inches) - once on each side. Therefore, the length of the box will be "w + 15 - 6" inches, which simplifies to "w + 9" inches.
5. The height of the box will be equal to the size of the square (3 inches).
Now, we can calculate the volume of the box:
Volume = Length x Width x Height
750 = (w + 9) x (w - 6) x 3
By simplifying the equation, we can find the value of "w" and proceed to find the original dimensions.
Let me calculate the original width and length for you.
To find the original dimensions of the piece of metal, we need to break down the problem into smaller steps. Here's how you can solve it:
Step 1: Let's assume the original width of the metal piece is "x" inches.
Step 2: The length of the metal piece is given as 15 inches longer than it is white squares with size 3 inches longer cut from the four corners. So, if we cut squares of size 3 inches from each corner, the resulting length will be (x - 3 - 3) = (x - 6) inches.
Step 3: Now, to form an open box, we need to fold up the flaps created by cutting the squares. This will increase the height of the box by 3 inches. So, the height of the box is 3 inches.
Step 4: The formula for the volume of a rectangular box is length × width × height. We are given that the volume of the box is 750 inches^3. Substituting the dimensions from steps 2 and 3, we get:
(x - 6) × x × 3 = 750
Step 5: Simplifying the equation:
3x(x - 6) = 750
3x^2 - 18x = 750
3x^2 - 18x - 750 = 0
Step 6: Now we can solve this quadratic equation using various methods, such as factoring, completing the square, or using the quadratic formula. In this case, let's solve it using factoring.
Factoring the quadratic equation:
3(x - 30)(x + 5) = 0
Setting each factor equal to zero:
x - 30 = 0 or x + 5 = 0
Solving for x:
x = 30 or x = -5
Since the dimensions cannot be negative, we discard x = -5, leaving us with:
x = 30
So, the original width of the metal piece is 30 inches.
Step 7: To find the original length, we substitute x = 30 into the expression from step 2:
Length = (x - 6) = (30 - 6) = 24 inches
Therefore, the original length of the metal piece is 24 inches.
To summarize:
- The original width is 30 inches.
- The original length is 24 inches.
