If each grid is 1/2 and there are 5 grids for the length, 2 grids for the with and 3 grids for the height, then we will multiply one-half by the number of grids to find real lengths.
Length: 1/2 * 5 = 5/2
Width: 1/2 * 2 = 1
Height : 1/2 * 3 = 3/2
Now find the volume by multiply the length by the width by the height
