Question

find the total surface area and lateral surface area of the cube with side 4 cm

Answer 1

tsa=6a^
tsa =6*4*4
=96

lsa =4a^
lsa =4*4*4
=64

Answer 2

Hi ,

Let the side of a cube = a

a = 4 cm ( given )

i ) Total surface area of the cube = ( TSA )

= 6a²

= 6 × ( 4 cm )²

= 6 × 16 cm²

= 95 cm²

ii ) Lateral surface area = LSA

= 4a²

= 4 × ( 4 cm )²

= 4 × 16 cm²

= 64 cm²

I hope this helps you.
