Angie packed same-size cubes into a rectangular prism.
What is the number of cubes needed to fill this prism?
20 cubes
35 cubes
36 cubes
36 cubes
Image shows a base of cubes 3 units long, 2 units wide, and with a column of cubes 1 cube wide and 7 cubes tall.
If the base of the prism is 3 units long by 2 units wide, then the number of cubes in the base would be 3 x 2 = 6 cubes.
Adding the column of 7 cubes to the base, the total number of cubes needed to fill the rectangular prism would be 6 (base) + 7 (column) = 13 cubes.
Therefore, 13 cubes would be needed to fill this prism.
