Question

in a cuboid, the sum of the squares of the three dimensions equal half its total surface area and its volume is 729 centimetre cube . Find the lateral surface area

PLEASE PROVIDE ME WITH THE STEPS ALSO, THANK YOU:)

Answer 1

Answer:

Let the side of a cube be a cm

As we know that

Volume of a cube with side a is a³

Given volume of a cube is 729 cm³

⟹a³ =729

⟹a=9

Surface area of cube is 6a² = 6×9²

=486 cm²
