Question

There is a cube of 64 identical pieces . How many more such small cubes will be required to cover this cube completely ?
A/ 150
B/ 151
C/ 152
D/ 48 ​

Answer 1

Step-by-step explanation:

For cube we will use formula

L×b×h=4×4×4=64

Cubes painted on 3 sides=8

2 sides=2×12=24

1 side =4×6=24

Then sum of all three=8+24+24=56

It means that the cube with no colored face will be=64–56=8
