Answer:
10 half unit cubes
Volume = 1 1/4 unit³
Step-by-step explanation:
Volume of rectangular prism = Length * width * height
From the dimensions given in the picture :
Volume = 1 * 1/2 * 2 1/2
Volume = 1 * 1/2 * 5/2
Volume = 5/4 unit³
Volume = 1 1/4 unit³
Number of half unit cube per unit³ = 8
Total number of half unit cubes that will fill it:
Number of half unit cube per unit³ * volume
8 * 5/4
= 40 /4
= 10
