Class 6 was set the Maths challenge..
Today we are stepping out of the classroom and into the shoes of City Architects. We have been hired to build a brand new 3D ‘Cubic City’, but there is a catch. The City Mayor will only let us build if we can calculate exactly how much space our buildings take up.
When we measure flat space—like the carpet we are sitting on—we look at the area. But buildings aren’t flat! They have 3D volume. Volume just means how many tiny blocks could fit inside that building if we filled it like a box of blocks.
Instead of filling our cardboard buildings with real blocks, we can use a mathematical superpower formula:
- Length: How long is it across the front?
- Width: How deep does it go back?
- Height: How tall is it?
Multiply those three numbers together, and you get the volume in cubic centimetres, which we write as cm3. That little floating 3 is our secret code for 3D!
