To find the surface area of a rectangular prism, use the formula:
Surface Area = 2(lw + lh + wh)
Where l = length, w = width, and h = height.
Given the dimensions:
l = 4in, w = 2.25in, and h = 8in
Surface Area = 2(4*2.25 + 4*8 + 2.25*8)
Surface Area = 2(9 + 32 + 18)
Surface Area = 2(59)
Surface Area = 118 square inches
The surface area of the rectangular prism is 118 square inches.
What is the surface area of the rectangular prism?(1 point) 4in, 2.25in, and 8
