A. There will be 6 layers of cubes because each cube has a height of 1/2 and 3x2=6

B. The perimeter of the base is 24cm.

2l+2w=p
2(8)+2(4)=p
16+8=p

A. 6

There will be 6 layers of cubes, since the height is 3 centimeters and the height of the cubes is 1/2

B. 24

The perimeter is the formula 2l+ 2w. With the length and width being 8 and 4, you get 16+8 which is 24 for the perimeter of the base
