Question

A prism is completely filled with 80 cubes that have edge length of 1/2 cm what is the volume of prism

Answer 1

`\begin{gathered} \text{Volume of cube=a}^3 \\ \text{where 'a' represent one side of the cube} \end{gathered}`
`\text{Edge length of cube is }(1)/(2)cm`

Thus,

`\begin{gathered} \text{Volume of cube=(}(1)/(2))^3 \\ \text{Volume of cube=}(1)/(8)cm^3 \end{gathered}`

80 cubes will have a volume of:

`80*(1)/(8)=10`

Hence, the volume of the prism is 10 cubic metre
