Answer:
D) 3.28
Step-by-step explanation:
820/x=100/2.5
(820/x)*x=(100/2.5)*x       - we multiply both sides of the equation by x
820=40*x       - we divide both sides of the equation by (40) to get x
820/40=x
20.5=x
x=20.5
now we have:
2.5% of 820=20.5

Answer:
24 m³
Step-by-step explanation:
Since you didn't state the dimensions of the rectangular prism, and you didn't add a picture to show it's dimensions, then permit me to assume dimensions for the question 
Assuming it's breadth is 2 m. 
Assuming it's length is 4 m. 
Assuming it's height is 3 m
Then the volume of a rectangular prism is given as l * b * h. Which means we multiply all the sides by one another. From my assumption of values, we have that 2 * 3 * 4, and this gives us 24 m³
24 m
Now what you'd do is substitute your values for my assumed values.. Cheers
