Question

What is the surface area of the figure? 210 in.2 600 in.2 1,090 in.2 280 in.2

Answer 1

Hey There!

The formula to calculate for surface area is

2(wh + lw + lh)

Let's plug these numbers in.

2(7*20 + 15*7 + 15*20)

Calculate

7 * 20 = 140

15 * 7 = 105

15 * 20 = 300

Add these numbers up

300 + 105 + 140

= 545

Multiply 545 * 2 = 1090

Therefore, the surface area of the figure would be 1090in
`^2`

Hope this helped!
