Question

A rectangular prism has a length of 5 1/4 m, a width of 4 m, and a height of 12 m. The prism can be filled with unit cubes that have edge lengths of 1/4 m. (6th grade math) need to help brother :)

Answer 1

find total volume
volumetotal/volumecube=number of cubes

volume total=length time width times height

length=5 and 1/4=5.25
width=4
height=12
volmetotal=5.25 times 4 times 12=252 cubic meters

volume cube=side^3
side=1/4
volume cube=(1/4)^3=1/64




vtotal/vcube=252/(1/64)=252*64=16128


16128 cubes can fit
