Find the volume of a rectangular prism with the following dimensions:
L = 5 inches
W = 8 inches
H = 2 inches
80 cubic inches
2/6 + 5/6 =
7/6 or 1 and 1/6
7/8 - 3/8 =
4/8 or 1/2
What is 1/3 of 30?
10
Use partial products to solve 24 x 9.
(20 x 9) + (4 x 9) = 180 + 36 =216!
Find the volume of a rectangular prism with the following dimensions:
L = 8 inches
W = 13 inches
H = 10 inches
1040 cubic inches
3/4 + 5/8 =
11/8 or 1 and 3/8
1/2 - 3/16 =
5/16
What is 1/5 x 100?
