The question
Question: find the volume of a prism with base area 15 m² and length 6 m.
1 Base times length
A prism has the same shape all the way through.
The face at the end is the base.
Its area is A = 15 m².
The prism is that base, stacked up 6 m long.
Like the circle of a cylinder.
So the volume is V = A × length.
V = A × length
Now put the numbers in: A = 15 and length = 6.
V = 15 × 6
15 times 6 is 90.
We count cubes, so the unit is m³.
So the volume is 90 m³.
V = 90 m3
Answer
V = 90 m3
