Two cubes have surface areas of 72 square feet and 98 square feet. what is the ratio of the volume of the small cube to the volu

Serjik [45]

Let's denote the sides of the small and bigger cubes a and b respectively. Then, we can write that 6 $a^{2}$ =72, a= $2\sqrt{3}$ and 6 $b^{2}=98, b=[tex] \frac{7}{sqrt{3}}$ . The volume of the smaller cube is $2 sqrt{3} ^{3}$ = $24 sqrt{3}$ . The volume of the bigger cube is $\frac{7}{sqrt{3}}^{3}$ = $\frac{343}{3sqrt{3}}{$ . We have to find $\frac{24 sqrt{3}}{frac{343}{3sqrt{3}}$ = 216/343
