A 3D shape with ... 130 = 360 cm². The area of the cross-section is given, 8 cm². The area of the cross-section is multiplied by the length, 8 × 20 = 160. The volume of the prism is 160 cm³.

The volume of any cylinder is the area of the cross-section multiplied by its height. This is given by the formula \(V\) = π\(r\)²\(h\) , where \(r\) is the radius of the circular cross-section ...
