Question

Janey paints a block of wood with gold glitter for an art project. The block measures 8 inches by 10 inches by 20 inches. After she's done, she decides to make two blocks by cutting through the block on the red line. She still wants each block to be covered with gold glitter

1. what is the shape of each cut surface? What are its dimensions? and what is the total area of paint she still needs to paint?

2. What is the area of each cut surface?​

Answer 1

1. Square, 10in x 8in, 160in^2

2. Each surface has an area of 80in^2

Explanation:

1. Rectangle is the shape of each cut surface which is 10in by 8 in. Since the block was already painted with glitter, she needs to paint both sides of the cut surface only, 2*8in * 10in = 160in^2.

2. Each cut will have a surface area of 10in * 8in = 80in^2
