Question

1. Andre is building a tower out of different foam blocks. These blocks come in three different thicknesses: -foot, -foot, and foot. Andre stacks two-foot blocks, two-foot blocks, and two-foot blocks to create a tower. What will the height of the tower be in foot? Explain or show how you know.

Answer 1

Answer:

Height of the tower = 1.75 ft

Explanations:

The thickness of the blocks are 1/2 ft, 1/4 ft, and 1/8 ft

Two 1/2 ft blocks will have a thickness of:

2 x 1/2 = 1 ft

Two 1/4 ft blocks will have a thickness of:

2 x 1/4 = 1/2 ft

Two 1/8 ft blocks will have a thickness of:

2 x 1/8 = 1/4 ft

The height of the tower = 1 + 1/2 + 1/4

The height of the tower = (4 + 2 + 1) / 4

The height of the tower = 7/4 = 1.75 ft
