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 the cut surfaces she still needs to paint?

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

Answer: 160 square inches

if the block is cut after it’s been painted, two sides with the same measurements don’t have glitter on them. you find the area of the one rectangle and multiply it by 2 as follows:

A = length • width

A = 10 • 8 = 80

area that needs to be covered = 80 • 2 = 160 square inches

Step-by-step explanation: I just knowww
