From the given figure
The prism formed from 5 cubes long, 2 cubes wide, and 2 cubes height, then
Its length = 5 cubes
Its width = 2 cubes
Its height = 2 cubes
Since the side of each cube = 1/2 cm, then
Its length = 5 x 1/2 = 5/2 cm
Its width = 2 x 1/2 = 1 cm
Its height = 2 x 1/2 = 1 cm
The volume of the prism = length x width x height, then
[tex]\begin{gathered} V=\frac{5}{2}\times1\times1 \\ V=\frac{5}{2}cm^3 \end{gathered}[/tex]
The volume of the prism is 5/2 cubic cm
The answer is A
