# Factorising exam questions watch

1. Can anyone help me please ive tried but dont understand

2. For the show that would you not multiply the three given dimensions to make it equal to 924 then take that from both sides to make it =0
3. so to get the volume of a cuboid you multiply the length, width & height...

here 4*(x + 1)*(x + 11)

we are told it equals 924...

4(x + 1)(x + 11) = 924

now you can divide through by 4

(x + 1)(x + 11) = 231

then multiply out the brackets & make sure there is a zero on the right hand side.

after that it is just factorising and solving in the usual way.
