If something is a perfect cube, it is able to be put under a cube root ( $\sqrt[3]{..}$ ) and will result in an integer (a non-decimal number > 0, basically).

So let's calculate $\sqrt[3]{48}$ , and see if the result is an integer.

$\sqrt[3]{48}$ = 3.634.......

As you can see, the result is not an integer, therefore 48 is not a perfect cube.

An amount was shared in the ratio 8:6:9:14:12.The largest share was56.What was the total amount shared?

lutik1710 [3]

Answer:

196

Step-by-step explanation:

Since the largest share was 56 and the largest ratio is 14, then

56 ÷ 14 = 4 ← value of 1 part of the share, thus

8 parts = 8 × 4 = 32

6 parts = 6 × 4 = 24

9 parts = 9 × 4 = 36

14 parts = 14 × 4 = 56

12 parts = 12 × 4 = 48

Total the amounts

total = 32 + 24 + 36 + 56 + 48 = 196
