Question

Can someone help? What’s the answer.

Answer 1

The surface area of the red square is 180, and the surface area of the blue square is 328. So the full answer is 508.

Explanation:

A = 2( width times length +height times length +height times width ) = 2(6 times 3 + 8 times 3 + 8 times 6)=180

A = 2(width times length + height times length + height times width) = 2(2 times 12 + 10 times 12 + 10 times 2) = 328

And 328 + 180 = 508.
