Question

You are stacking wooden blocks (cubes) whose sides are all 1 1/4 inches how many blocks do you need to stack or build a block tower that is 7 1/2 inches tall

Answer 1

Answer: You need to stack 6 blocks to build the block tower.

Explanation:

Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).

Mathematically speaking:

7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes

You need to stack 6 blocks to build the block tower.
