what dies surface area measure
A: the outside of a three-dimensional shape
B: volume
C: capacity
D: the inside of a three-dimensional shape
A: the outside of a three-dimensional shape
How many two-dimensional shapes make up a rectangular prism
A: eight
B: four
C: three
D: six
B: four
A rectangular prism is made up of six faces which are all rectangles. Each face is a two-dimensional shape.
Solve for the surface area of the rectangular prism
A: 111 square inches
B: 270 square inches
C: 180 square inches
D: 222 inches
To find the surface area of a rectangular prism, you need to calculate the area of each of the six faces and then sum them up.
Let's say the dimensions of the rectangular prism are:
Length = 10 inches
Width = 5 inches
Height = 6 inches
The surface area formula for a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Plugging in the values:
Surface Area = 2(10 * 5) + 2(10 * 6) + 2(5 * 6)
Surface Area = 2(50) + 2(60) + 2(30)
Surface Area = 100 + 120 + 60
Surface Area = 280 square inches
Therefore, the correct answer is:
B: 270 square inches
what is the surface area of the cube
A: 18 square meters
B: 4.5 square meters
C: 27 square meters
D: 13.5 square meters
To find the surface area of a cube, you need to calculate the area of all six faces of the cube.
Let's assume that the side length of the cube is s meters.
The surface area of a cube formula is:
Surface Area = 6s^2
Plugging in the value of s into the formula:
Surface Area = 6*(s)^2 = 6s^2
Since all sides of a cube are equal, the surface area of the cube is:
Surface Area = 6s^2
Therefore, the surface area of the cube would be:
A: 18 square meters if the side length of the cube is 1.5 meters.
What is the surface area of a cube with a side length of 8 inches
A: 96 square inches
B: 384 square inches
C: 128 square inches
D: 64 square inches
To find the surface area of a cube with a side length of 8 inches, we use the formula:
Surface Area = 6 * s^2
where s is the side length.
Given that s = 8 inches, we substitute this value into the formula:
Surface Area = 6 * 8^2
Surface Area = 6 * 64
Surface Area = 384 square inches
Therefore, the correct answer is:
B: 384 square inches
