The volume of a cubed shaped music box is 512 cubic centimeters find the surface area of the music box
AfilCa [17]

The surface area of music box is 384 square centimeter

<em><u>Solution:</u></em>

Given that,

Volume of cubed shaped music box = 512 cubic centimeter

To find: Surface area of music box

<em><u>The volume of cube is given as:</u></em>

volume = a^3

Where, "a" is the length of side

Therefore,

512 = a^3

Taking cube root on both sides,

a = \sqrt[3]{512}

a = \sqrt[3]{8 \times 8 \times 8}\\\\ a = \sqrt[3]{8^3}

a = (8^3)^{\frac{1}{3}}

a = 8

Thus length of side of cube is 8 cm

<em><u>Find surface area of cubed shaped music box</u></em>

<em><u>The surface area of cube is given as:</u></em>

A = 6a^2

Substitute a = 8 in above formula

A = 6(8)^2\\\\A = 6 \times 64\\\\A = 384

Thus surface area of music box is 384 square centimeter
