If the diagonal of a cube is 4root3 cm , then perimeter of the cube =?

Answer 1

diagonal of a cube= root 3 a where a is the side

here he diagonal is 4root 3
so the side is 4 units

perimeter is 12*4 = 48 units

Answer 2

Hey there !

Side of a cube = a

Diagonal of a cube = √3a = 4√3

√3a = 4√3

a = 4√3 ÷ √3

a = 4 cm

Perimeter of a cube = 12a
= 12 × 4 = 48 cm
