Here's the solution,

we know that,

<em><u>v</u></em><em><u>o</u></em><em><u>l</u></em><em><u>u</u></em><em><u>m</u></em><em><u>e</u></em> (v) = l × w × h

where,

  • l = length
  • w = width
  • h = height

So,

=》

v = l \times w \times h

=》

720 = 10 \times 8 \times h

=》

720 = 80 \times  h

=》

h =  \dfrac{720}{80}

=》

h = 9

so, value of <em><u>height</u></em> (h) = 9 ft
