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



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


Answer:
the C one is 18in and the E one is 12in
Step-by-step explanation:
You might need to give out the choices, if there are any. thanks for asking.
For the first one we divide every element by sqrt3
we get
q+2/sqrt3 =sqrt5/sqrt3
q=(sqrt5-2)/sqrt3
q=sqrt3*sqrt5-2*sqrt3/3
q=sqrt15-2sqrt3/3
which is the third option
For the second one
sqrt(2y-5) +4=8
first we move the 4 to the right
sqrt(2y-5)=4
we remove the square root by bringing to the power of two
2y-5=16
2y=21
y=21/2
y=10 1/2
third option
