Respuesta :
the answer is d because you would take 4 x 4 x 5 and then you divide and you get 80
Dimensions of bigger box = 4ft x 4ft x 5ft
or, 48 in x 48 in x 60 in (Because 1 ft = 12 inch)
We know that, volume of a cuboid is:
V = length x breadth x height
Volumeo f big box = 48 x 48 x 60
= 138240 cubic inch.
Edge length of cube shape box = 12 inch
For cube, volume = edge^3
Volume of cube = (12)^3
= 1728 cubic inch
Number of cube shaped box that can fit into big box = Volume of big box / Volume of cube shaped box
= 138240 / 1728
= 80
Hence, correct answer is D-80.
