What is the formula for the volume of a prism?
Show answer
Volume = area of cross-section × length.
Why does an L-shaped solid count as a prism?
Show answer
Its cross-section (the L-shape) is identical all the way along its length.
How do you find the cross-sectional area of an L-shaped prism?
Show answer
Split the L-shape into two rectangles, find each area, and add them together.
A prism has cross-sectional area 30 cm² and length 12 cm. What is its volume?
Show answer
360 cm³ (30 × 12).
How do you find the length of a prism from its volume and cross-sectional area?
Show answer
Length = volume ÷ cross-sectional area.
A prism has volume 300 cm³ and cross-sectional area 25 cm². What is its length?
Show answer
12 cm (300 ÷ 25).
How many cm³ are in 1 m³?
Show answer
1,000,000 cm³ (100 × 100 × 100).
Before finding a prism's volume in m³, what must you do with lengths given in cm?
Show answer
Convert them to metres first (divide by 100), so all dimensions are in the same unit.
