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}

so

<u>Find the value of the scale factor</u>

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

<u>Find the surface area of the smaller solid</u>

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

<u>the answer is</u>

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