Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box = ft
Height of the box = 2 ft
Volume of the box = length × width × height
= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube = ft
Volume of the cube = length × length × length
Volume of the cube = 0.125 ft³
= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.
