The volumes of two similar solids are 210 m3 and 1,680 m3. The surface area of the larger solid is 856 m2. What is the surface a

Ksju [112]

we know that

$scale \ factor^{3}=\frac {volume\ larger\ solid }{volume\ smaller\ solid}$

Find the value of the scale factor

$volume\ larger\ solid= 1,680\ m^{3} \\ volume\ smaller\ solid= 210\ m^{3}$

substitute the values in the formula

$scale \ factor^{3}=\frac {1,680 }{210}$

$scale \ factor^{3}=8$

$scale \ factor=\sqrt[3]{8} \\ scale \ factor= 2$

Find the surface area of the smaller solid

we know that

$scale \ factor^{2}=\frac {surface\ area\ larger\ solid }{surface\ area\ smaller\ solid}$

$surface\ area\ larger\ solid =856\ m^{2} \\ scale\ factor =2$

$surface\ area\ smaller\ solid= \frac{surface\ area\ larger\ solid}{scale \ factor^{2}}$

substitute the values

$surface\ area\ smaller\ solid= \frac{856}{2^{2}}$

$surface\ area\ smaller\ solid=214\ m^{2} }$

therefore

the answer is

The surface area of the smaller solid is equal to $214\ m^{2}$
