Question

Find the total surface area and lateral surface area of a cube whose edge is :
(i) 10 cm
(ii) 25 cm​

Answer 1

total surface area of cube = 6a²

lateral surface area of cube = 4a²

i) edge = 10cm

T.S.A. = 6(10)²

=6×100 = 600cm²

L.S.A. = 4(10)²

= 4×100=400cm²

ii) edge = 25cm

T.S.A. = 6(25)²

= 6×625=3750cm²

L.S.A. = 4(25)²

= 4×625 = 2500cm²

I hope this answer helps you.
