Tasha has foam blocks stored in a box that measures 3 1/4 ft long by 3 ft wide by 1 ft tall.

Question

Each foam block is a cube with 1/4 ft edge length. How many blocks can fit into the box?



A)156

B)312

C) 624

D) 2496

Answer 1

I thought you said these problems were all different. They look exactly the same to me.

Figure the volume of one of the small blocks, and use that to divide into the whole volume.

3 1/4 = 13/4 so the box has a volume of 13/4 * 3 * 1 = 39/4 ft^3

each small block has a volume of (1/4)^3 = 1/64 ft^3

(39/4) / (1/64) = 624

Answer 2

Thank you for explaining.
