Question

1 square = 1 m

Live measurements

Total perimeter 0 m

Total area 0 m²

Length 3 m Width 2 m Height 2 m

Radius 1.5 m Height 3 m

Base 3 m Triangle height 2 m Depth 4 m

Box measurements

Volume 3 × 2 × 2 = 12 12 m³

Surface area 2(3×2 + 3×2 + 2×2) = 32 32 m²

Unfolded net

This is how much flat material it takes to make the box.

Pythagoras' theorem

a = 3 m b = 4 m c = √(a² + b²)

c = √(9 + 16) = √25 = 5 m

The diagonal of a right-angled rectangle is the hypotenuse of the right triangle formed by the two sides.
