Question

the volume and the total surface area of a cube are V and S respectively..if the edge of the cube is made three times of volume and the total surface area become V' and S' respectively. find (1)V':V (2) S':S

Answer 1

Answer:

V=lbh,S=2(lb+bh+lh)

d=√(l²+b²+h²)

V'=(2l)(2b)(2h)=8lbh

S'=2((2l)(2b)+(2b)(2h)+(2l)(2h))

=4×2(lb+bh+lh)

d'=√((2l)²+(2b)²+(2h)²)

=√(4(l²+b²+h²))

V'/V=8;S'/S=4;d'/d=2
