Question

if the lateral surface area of a cube is 600cm2, then find the total surface area is

Answer 1

csa=4a*2

so 4a*2=600

600/4=a*2

√150=a

so,tsa=6a*2

6*√150*√150

6*150

900cm*2

Answer 2

lateral surface area of cube = 4a^2=600

a^2 = 150

a = 5√6

TSA = 6a^2

6*150. (a^2 = 150)

TSA = 900cm^2
