To solve this, we use the formula for the volume of the frustum of a cone which is expressed as:

<span>V= (H/6)[WL + (W+a)(L+b) + ab]
</span>V = 3/6 [(6 ft. × 8 ft.) + (6 + 14)(18 + 8) + (<span>14 ft. × 18 ft.)]

Convert into mixed number 81/3 and -29/2
LuckyWell [14K]
Hmmmm to convert from improper to mixed, simply do the division of both, the quotient gets upfront, the remainder as the numerator, for example,

how many times 3 goes into 81?  well, 27 times, with a remainder of 0, thus  \bf 27\frac{0}{3}

how many times does 2 go into 29?  well  14 times, with a remainder of 1, thus  \bf -14\frac{1}{2}
