Solids X and Y are similar.

X has volume of 64 cm3

Y has volume of 729 cm3

The surface area of X is 208 cm2

Work out the surface area of Y.

Answer: 2,369.25 cm3

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

X has volume of 64 cm3 and s surface area of 208 cm2

The proportion is = volume / surface area = 64/208

Y has volume of 729 cm3

Volume / surface area = 729 / s (surface area of y)

64/208 = 729 / s

Solving for s:

s = 729 / (64/208)

s = 2,369.25 cm3
