A cube has a surface area of 37 1/2. What's the volume?
Dmitry [639]

Here's the solution,

let the sides of cube be a

now, we know

<em><u>Surface area </u></em>=

6 {a}^{2}

So,

=》

6 {a}^{2}  = 37 \dfrac{1}{2}

=》

6 {a}^{2}  = 37.5

=》

{a}^{2}  = \dfrac{37.5}{6}

=》

{a}^{2}  = 6.25

=》

a =  \sqrt{6.25}

=》

a = 2.5 cm

Each side of <em><u>cube</u></em> measures 2.5 cm

<em><u>volume</u></em> :

=》

{a}^{3}

=》

2.5 \times 2.5 \times 2.5

=》

15.625

=》

15 \dfrac{5}{8}  \: cm {}^{3}
