A pyramid is a 3D shape that has a polygonal base and triangular faces that meet at an apex.

The apex is the point (vertex) which is the greatest perpendicular distance from the base.

When the apex lies directly above the centre of the base, then it is called a right pyramid.

An oblique pyramid is when the apex is not directly above the centre of the base.

Problem solving with further surface area and volume

In this unit, pupils have increased their knowledge of volume which is used in the compound measures unit as the formula for density involves volume. 

In the prior unit, pupils built upon their learning of the area of different shapes. In this unit, pupils will continue to further develop their understanding of shapes by considering surface area and volume of pyramids, spheres and cones.

The net of a cylinder is made from two congruent circles and a {{ }}.

A cylindrical tube is cut and unfolded into a rectangle. Find the values of $$a$$ and $$b$$ on the lengths of the rectangle.

Surface area of curved surface = $$ 2\pi  r h$$

Surface area of curved surface = $$ \pi  r h$$

Surface area of curved surface = $$ \pi  r^2 h$$

Surface area of curved surface = $$2 \pi r^2 + 2\pi  r h$$

Surface area of curved surface = $$ 2\pi  r^2 h$$

Which formula gives the surface area of the curved surface of a cylinder of radius $$r$$ and height $$h$$?
