Question

find the volume of the cube whose lateral surface area is 196cm^2

Answer 1

LSA of cube=4a²
194=4a²
a²=196/4
a=√49
a=7 cm
Volume=a³
            =7³
            =343 cm³

Answer 2

Lateral surface are of cube = 196cm^2
4(a)^2 = 196 cm^2
a^2 = 196 /4
a^2 = 49 cm
a = √49
a = 7 cm
Volume of cube = a^3
= 7^3
= 343 cm^3
