Answer:

i know the answer for question 8 & 9

8) Volume is the amount of space a 3D shape takes up.

A cubic cm block takes up 1 cubic cm. This is written as 1 cm³.

You can work out the volume of a shape by multiplying height × width × depth.

If the shape is made of cubic cm blocks, you can count the cubes to find the shape's volume.

9) The face or surface of a solid on its sides. That is, any face or surface that is not a base. See also. Lateral surface area, prism, pyramid, cone, cylinder.
