Lateral area of the prism excluding the two ends: (3*20)+(4*20)+(5*20) = 240 square units
240 units squared
Say, a rectangular prism.... height: 8cm length: 5cm width: 4cm 5x4x8 5x4=20 20x8=160 And remember, volume is always cubed. Volume of the rectangle = 160cm3 HOPE THIS SOMEHOW HELPED YOU ;3
A prism whose ends are 18-gons.
20*20*20=8000
A square-based pyramid and a trapezoidal prism.
Lateral area of the prism excluding the two ends: (3*20)+(4*20)+(5*20) = 240 square units
Volume of rectangular prism: 5*5*20 = 500 cubic cm
20. You multiply all three numbers together to get volume because volume = length X width X height. :D
I'm going to assume you mean a rectangular container. Volume for a rectangular prism: Volume = length*width*height. So, 20 in * 16 in * 10 in = 3,200 cubic inches.

A heptagonal prism has 20 edges.
20
The volume V of a prism is the product of the area base and the height h of the prism. V = Bh or V = LWh substitute what we know into the formula; 63 = (5)(W)(4) 63 = 20W divide by 20 to both sides; 3.15 = W Thus, the width is 3.15 cm.
