Non-calculator Qu
Came across following question, on GCSE Non-calculator.
at first glance it lookd do-able, but then it wasn't.
Surface area of a cube is 60cm(sq).
What is the volume?
Got to 10cm(sq).. for one side, but without a calculator I'd think it was pretty difficult to get the sq root of 10.
Any advise wecome...
Maybe a different approach?
