The number of calories in one
croissant can be expressed as six cubed. Determine the whole number that
represents six cubed.

We know that when we raise a number
to the power of three, we want to cube the number. This involves multiplying the
number by itself and itself again. Six cubed is equal to six
multiplied by six multiplied by six. We know that six multiplied by six
is 36, so we need to multiply this by six. One way of doing this is using the
grid or box method. We split 36 into its tens and ones,
so we have 30 and six. As three multiplied by six is 18,
30 multiplied by six is 180. We know that six multiplied by six
is 36.

We can then find the sum of 180 and
36 using column addition. Zero plus six is equal to six. Eight plus three is equal to 11, so
we need to carry the one. This leaves us with an answer of
216. The whole number that represents
six cubed is therefore 216. This means that there are 216
calories in one croissant.
