How many 1/2 inch cubes can fit in a rectangular prisim with length of 2 height of 3/2 and width of 1.
Mrac [35]

Answer:

X=6

Step-by-step explanation:

From the question we are told that

Length l=2

Height h=3/2

Width w=1

Generally the equation for Volume of the Rectangular prism is mathematically given by

 v=l*h*w

 v=2*\frac{3}{2}*1

 v=3m^3

Therefore the number of half 1/2 inch cube X in v is

 X=\frac{v}{1/2}

 X=6

6.5 + (−2) + 10.5 I could probably do this but its kind of hard to understand. Explain?
elena-s [515]
Hello! Let's work this problem from left to right to make things a bit easier ;)

6.5+(-2) is the same as 6.5-2, since adding a negative is the same as subtracting a positive. 6.5-2=4.5

Now, we have to add 10.5 to 4.5, which gives us the grand total of 15. I hope this helped! Let me know if you need anything else!
