Ricky is filling an 8 inch by 4 inch by 4 1/2 inch rectangular box with packing peanuts. The peanuts are cubes that come in two different sizes ,1 cubic inch and 1/8 inch .How many peanuts of each size are needed to fill the box?
First find the volume of the box: 8•4•4.5=144 cubic inches. 8 of the 1/8 inch=1 of the 1 cubic inch He could do 144 and 0 143 and 8 142 or 16 Or just keep following the pattern... Hope that helped
