Question

Use the formula SA=2(lw)+2(wh)+2(LH) to find the surface area for a rectangular prism with the length of2.9 ​, a width w of 1.23m ​, and a height h of 7m .

Answer 1

To find the surface area of a rectangular prism, we can use the formula:

SA = 2(lw) + 2(wh) + 2(LH)

where SA is the surface area, l is the length, w is the width, h is the height, and L is the length.

Substituting the given values, we get:

SA = 2(2.9 x 1.23) + 2(1.23 x 7) + 2(2.9 x 7)

SA = 5.634 + 17.22 + 40.6

SA = 63.454 m^2

Therefore, the surface area of the rectangular prism is 63.454 square meters.
