Solve for the surface area of the rectangular prism.
(1 point)
111 square inches
180 square inches
270 square inches
222 square inches
Surface area = 2lw + 2lh + 2wh
Surface area = 2(3)(5) + 2(3)(12) + 2(5)(12)
Surface area = 30 + 72 + 120
Surface area = 222 square inches
Therefore, the surface area of the rectangular prism is 222 square inches.
1.5 m
What is the surface area of the cube?
(1 point)
27 square meters
18 square meters
13.5 square meters
4.5 square meters
A cube has all sides of equal length. The equation for the surface area of a cube is:
Surface area = 6s^2
Where s is the length of one side.
Given that the length of one side is 1.5 m, we can substitute this value into the equation:
Surface area = 6(1.5)^2
Surface area = 6(2.25)
Surface area = 13.5 square meters
Therefore, the surface area of the cube is 13.5 square meters.
