Question

The dimensions of metallic cuboid are 100cm×80cm×64cm.it is metalled and recast into a cube. find the surface area of cube​

Answer 1

Ohh...yaah

So let's find the volume of the cuboid

So volume of the cuboid= L×b×h= 100×80×64=512000

So....since it's recast into a cube, the cube also will have the same volume

So... formula of volume of cube=a³=512000

So a=80

So area of one side of the cube=a²=6400

So...since a cube has 6 faces,

total surface area of the cube=6×6400

=38400sq.units
