Question

Clare is using little wooden cubes with edge length 1/2 inch to build a larger cube that has edge length 4 inches. How many little cubes does she need?

Answer 1

Answer: Clare would need 8 cubes.

               It's quite simple to get the answer for this, simply divide the edge lengths together

$\frac{4}{1/2}$

=$\frac{4}{0.5}$

= 8.

Answer 2

Answer:

Clare needs 8 little cubes.

Step-by-step explanation:

Edge length of larger cube = 4 inches

Edge length of little cubes = 1/2 inch

Number of little cubes needed = edge length of larger cube ÷ edge length of little cube = 4 ÷ 1/2 = 4 × 2/1 = 8

She needs 8 little cubes.
