Question

which expression can be used to find the surface area of the following rectangular prism A 15+10+6B 15+15+15+6 C 6+6+10+10+15+15D 6+10

Answer 1

C. 6 + 6 + 10 + 10 + 15 + 15

Step-by-step explanation:

The surface area of a rectangular prism can be calculated as:

Surface Area = lw + lw + wh + wh + lh +lh

Where l is the length, w is the width, and h is the height.

So, replacing l by 3, w by 2, and h by 5, we get:

Surface Area = 3(2) + 3(2) + 2(5) + 2(5) + 3(5) + 3(5)

Surface Area = 6 + 6 + 10 + 10 + 15 + 15

Therefore, the expression that can be used to find the surface area is:

Surface Area = 6 + 6 + 10 + 10 + 15 + 15
