Calculate the surface area of a right rectangular prism with the dimensions w= 12 in l = 18 in and h =8 in how many square inches is the surface area
To calculate the surface area of a right rectangular prism, you need to find the area of each face and add them together.
The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2wl + 2lh + 2wh
Given:
w = 12 in
l = 18 in
h = 8 in
Surface Area = 2(12)(18) + 2(18)(8) + 2(12)(8)
Surface Area = 432 + 288 + 192
Surface Area = 912
The surface area of the right rectangular prism is 912 square inches.
Calculate the surface area of a cube with 12 inch edges how many square inches is the surface area
To calculate the surface area of a cube, you need to find the area of each face and add them together.
Given:
Each edge of the cube = 12 inches.
Since a cube has six equal faces, the surface area of a cube can be calculated using the formula:
Surface Area = 6s²
Where s is the length of each edge of the cube.
Surface Area = 6(12²)
Surface Area = 6(144)
Surface Area = 864
The surface area of the cube is 864 square inches.
Calculate the surface area of a right rectangular prism each edge length is 15 ft
To calculate the surface area of a right rectangular prism, you need to find the area of each face and add them together.
Given:
Each edge of the prism = 15 feet.
Let's label the edges:
Length (l) = 15 ft
Width (w) = 15 ft
Height (h) = 15 ft
The surface area of a right rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
Substituting the given values:
Surface Area = 2(15)(15) + 2(15)(15) + 2(15)(15)
Surface Area = 2(225) + 2(225) + 2(225)
Surface Area = 450 + 450 + 450
Surface Area = 1350
The surface area of the right rectangular prism is 1350 square feet.
Sam needs to find the surface area of a cereal box for an art project the box is rectangular prism with the length of 8 inches and a height of 12 in and with a 2 in what is the surface area
To find the surface area of a rectangular prism, you need to calculate the area of each face and add them together.
Given:
Length (l) = 8 inches
Height (h) = 12 inches
Width (w) = 2 inches
To find the surface area, calculate the following areas:
Front and back faces:
Area = l * h = 8 * 12 = 96 square inches
Top and bottom faces:
Area = w * l = 2 * 8 = 16 square inches
Side faces (two of them):
Area = h * w * 2 = 12 * 2 * 2 = 48 square inches
Now add up the areas of all faces:
Surface Area = 2(front and back) + 2(side faces) + 2(top and bottom)
Surface Area = 2(96) + 2(48) + 2(16)
Surface Area = 192 + 96 + 32
Surface Area = 320
The surface area of the cereal box is 320 square inches.
Wrong
Apologies for the incorrect response. Let's calculate the correct surface area of the cereal box.
Given:
Length (l) = 8 inches
Height (h) = 12 inches
Width (w) = 2 inches
To find the surface area, calculate the following areas:
Front and back faces:
Area = l * h = 8 * 12 = 96 square inches
Top and bottom faces:
Area = w * l = 2 * 8 = 16 square inches
Side faces (two of them):
Area = h * w * 2 = 12 * 2 * 2 = 48 square inches
Now add up the areas of all faces:
Surface Area = 2(front and back) + 2(side faces) + 2(top and bottom)
Surface Area = 2(96) + 2(48) + 2(16)
Surface Area = 192 + 96 + 32
Surface Area = 320
The correct surface area of the cereal box is 320 square inches. I apologize for the confusion.
