Question

al surface area and the lateral surface area of the cubes whose edges are
(i) 13 cm
(i) 7 m
​

Answer 1

lateral surface area of the cube = 4s.s

I) LSA= 4.13.13

=676 cm2

ii) LSA= 4.7.7

=196 cm2

sorry for wrong ans

Answer 2

(i)The edge of cube=13cm

the surface area of cube =6a^2=6×13^2=1194cm^2

The lateral surface area of the cube

=4×a^2

=703cm^2

(ii)The edge of cube = 7cm

the surface area of the cube =6×a^2=6×7^2=294cm2

the lateral surface area of the cube

=4×a^2=4×7^2=196cm^2
