Rich task

Walt: solve a rich task.

Rich task

This task was extremely difficult to work out. There were no easy parts in this problem. The problem was to find out about how many people could have a normal dessert size piece of the cake. The cake was 4.8 metres long, 3 metres wide and 1 metre high. First, as a group, we worked out about what a normal size was and it was 512 cm cubed, because we all agreed that that amount was enough. Then we worked out about how much the actual size was. We converted the metres to centimetres. Then multiplied the answer by 512. The answer was 28,125.

4.8m x 3m x 1m cubed=
480cm x 300cm x 100 cm cubed=
480cm x 300cm=
144,000cm x 100cm
= 14,400,000cm cubed x 512
=28,125 cm cubed

It takes 28,125 people to eat a normal size piece of cake.
