Question

a metabolic cuboid of dimensions 100cm ×80cm× 64cm is melted and recast into a cube find the surface area of the cube ​

Answer 1

Answer:

38400

Step-by-step explanation:

total area of the cuboid = 4^3 × 20^3

area of the cuboid = area of the cube

4^3×20^3 = x^3( let the side of the cube be x cm)

=4×20 = x

therefore x=80

total surface area=

6×x^2

=6×80^2

=6×6400

=38400
