Question

A cuboid, with dimensions 28cm by 16cm by 15cm, has a volume of 6720cm cube. The cuboid is melted to form smaller cubes of length 4cm. How many cubes can be obtained?

Answer 1

Vol of the cube =Vol of cubiod

Vol of each smaller cube =s×s×s= 4×4×4=64

Vol of cuboid /Vol of each smaller cube = no of cubes that can be obtained

6720/64= 105

Hence 105 cubes can be obtained
