The following solid is a right pyramid with a square base. The pyramid has its apex, V, aligned directly above the centre of its base, W.
Calculate the length of AW, correct to two decimal places.
Hence, find the length of VW, correct to two decimal places.
Consider the cone with slant height of 13 m and perpendicular height of 12 m:
Find the length of the radius, r.
Hence, find the length of the diameter of the cone's base.
A right-angled triangular divider has been placed inside a box, as shown in the diagram:

A soft drink can has a height of 11 cm and a radius of 4 cm. Find L, the length of the longest straw that can fit into the can.
Round your answer down to the nearest cm, to ensure it fits inside the can.
A juice container has the shape of a rectangular prism. It needs a straw that must extend 20 mm beyond the container while touching the furthest corner of the base.
Find the exact length of the diagonal of the base, x.
Hence, find the length of the long diagonal of the juice container, z. Round your answer to two decimal places.
Hence, calculate the length of the straw needed. Round your answer to the nearest millimetre.
A builder needs to carry lengths of timber along a corridor in order to get them to where he is working. There is a right-angled bend in the corridor along the way. The corridor is 2 \text{ m} wide and the ceiling is 2.5 \text{ m} above the floor:
Calculate the maximum length of timber, in surd form, that would fit in the corridor when held parallel to the ground.
Since the corridor has a height of 2.5 \text{ m}, he can fit a longer piece of timber around the corner by angling it so that it reaches from the floor to the ceiling.
Find the maximum length of timber that is able to fit through the corridor, giving your answer correct to two decimal places.
