4.
Step-by-step explanation:
1. There are six sides of the cube and as side of cube is
5
cm and hence each side will have
5
×
5
=
25
one cubic centimeter cubes painted.
However, all the cubes on sides and corners will have painted sides more than one as they share with adjoining sides and only
3

3
=
9
one cubic centimeter cubes will have one side painted.
As there are six sides,
9
×
6
=
54
one cubic centimeter cubes will have exactly one of their sides painted.
3. Find the volume of a rectangular prism with a length of 15cm, width of 12cm and height of 7cm
L = 15 cm
Σ
W = 12 cm
H = 7 cm
Formula:
V=L. W. H
Solution:
V = 15-12-7
V = 1260
