Further volumes of prisms
Revision of Volume of Prisms
We have been learning about the volume of objects, particularly rectangular prisms, and then prisms more broadly.
$\text{Volume of any prism }=\text{Area of Base }\times\text{Height }$Volume of any prism =Area of Base ×Height
$V=A_b\times h$V=Ab×h
Units for Volume
It is probably worthwhile to remind ourselves of the units that are often used for calculations involving volume.
cubic millimetres = mm3
(picture a cube with side lengths of 1 mm each - pretty small this one!)
cubic centimetres = cm3
(picture a cube with side lengths of 1 cm each - about the size of a dice)
cubic metres = m3
(picture a cube with side lengths of 1 m each - what could be this big?)
AND to convert to capacity - 1cm3 = 1mL
Worked Examples
QUEstion 1

question 2
A hole is drilled through a rectangular box forming the solid shown. Find the volume of the solid correct to two decimal places.
