Question

What is the volume of the figure showing below? 5ft 6ft 10 1/2ft 2ft

Answer 1

Volume of a prism = Base area x height

The base is a trapezium

`\begin{gathered} \text{Base area = }(1)/(2)(a+b)h \\ =(1)/(2)(5+2)6 \\ =(1)/(2)(7)6 \\ =21ft^2 \end{gathered}`
`\begin{gathered} \text{Volume = 21 ft}^2\text{ x 10}(1)/(2)\text{ ft} \\ =21\text{ x }(21)/(2) \\ =220.5ft^3 \end{gathered}`
