Answer 1

why is a basketball a prism

Answer 2

Answer: 1,511 cm²

Explanation:

For this problem we will be finding the surface area, but not including the top.

This means we will have five sides to calculate for, see attached. Please note that the area of a rectangle can be found with A = L * W

[1] 19 cm * 10 cm = 190 cm²

[2] 19 cm * 10 cm = 190 cm²

[3] 29 cm * 10 cm = 290 cm²

[4] 29 cm * 10 cm = 290 cm²

[5] 19 cm * 29 cm = 551 cm²

Add them all together:

190 cm² + 190 cm² + 290 cm² + 290 cm² + 551 cm² = 1,511 cm²
