Answer:
200 in²
Step-by-step explanation:
The face consists of two 10 in squares. Each of those will have an area of ...
(10 in)² = 100 in²
so the two of them together will have an area of ...
2 × 100 in² = 200 in²
Do 3 x 3, which equals 9. Now put the Exponent of 3 next to the 9. Do 9 x 9 x 9, which is 81 x 9, which is 729.
Use the Pythagorean theorem to solve this problem. So, 81+x^2=1681. ( Pythagorean theorem: a^2+b^2=c^2). x^2=1600. x=40.
