To proof
Given: Length =12cm, width= 18cm, height = 22cm
volume of the rectangular prism (say V1) = length × breadth × height
= 12×18×22cm³
=4752 cm³
when dimensions are doubled
New length = 24 cm, New breadth =36 cm, New height =44 cm
volume of the rectangular prism (V2)= 24×36×44 cm³
= 38016 cm³
= 8(4752)cm³
This shows when the dimension doubled the volume of rectangular prism be 8 times the volume of the first one.
Therefore,
