Question

3. If the length of a diagonal of a cube is 12√3 cm, find its surface area and volume​

Answer 1

Diagonal = s root 3 where s= side
Therefore side = 12cm
Surface Area = 6s^2 = 6(12)^2 = 6(144) = 864 cm^2
Volume = s^3 = 12^3 = 1728 cm^3

Answer 2

Answer:

Diagonal=s root 3 where s=side

therefore side=12 cm

surface area=6s²

=6(12)²

=6(144)

=864 cm²

volume=s³

=12³

= 1728 cm³
