Volume of cube =a^3
2744=a^3
by making prime factors of 2744
2*2*2*7*7*7=a^3
2^3*7*3=a^3
by taking cube root on both sides
2*7=a
14=a
so<span> the length of its edge =14</span>
B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.
