Answer:
Height = 20 cm
Explanation:
Given the following data;
Length = 9cm
Breadth = 9cm
Volume of rectangular prism = 1620cm³
To find the height;
The volume of a rectangular prism is given by the formula;
Volume of rectangular prism = length * breadth * height
Substituting into the equation, we have;
1620 = 9 * 9 * height
1620 = 81 * height
Height = 1620/81
Height = 20 cm
