HI there !!
Edge of a cube = a
Lateral Surface Area = 4a² = 400 cm²
4a² = 400 cm²
a² = 400 ÷ 4
a² = 100
a = √100
a = 10cm
Edge of the cube = 10 cm
Edge of a cube = a
Lateral Surface Area = 4a² = 400 cm²
4a² = 400 cm²
a² = 400 ÷ 4
a² = 100
a = √100
a = 10cm
Edge of the cube = 10 cm

let "a" be the side of the cube.
LSA of a cube = 4a^2
its given that 4a^2=400
a^2=100
a=√100
a=10
thus side of the cube = 10cm
