Question

there is a solid cube which has been cut into two parts of equal volumes find the ratio of the total surface area of one of the cuboids to that of the given cube​

Answer 1

let the side of cube=a

now total surface area of cube=6a^2.

now you divide the cube in two equal cuboid then

total surface area of cuboid =

2a^2+4(a/2)^2

=3a^2

then ratio =3a^2/6a^2 =1/2
