How do you solve a math problem but by using the chunking strategy.

chunking is a maths method for dividing large numbers which can't be done mentally. It is the repeated subtraction of the divisor and its multiples. Put simply, it involves working out how many groups of a specific number fit into another number.

Step-by-step explanation:

this is what go.ogle says

So we want to know the area of the giftwrap that leann needs to cover a box that is 4in x 6in x 2in. so the box has the area a = 2* 4^2 in^2 + 2*6^2 in^2 + 2*2^2 in^2 and that is a= 2*16in^2 + 2*36 in^2 + 2*4in^2. so a= 32 in^2 + 72 in^2 + 8 in^2 = 112 in^2. so leann needs 112 in^2 of giftwrap.
