Answer:
114
Step-by-step explanation:
add the areas of all 6 faces
the formula is A= 2(l*w)+2(l*h)+2(h*w)
A=2(8*3)+2(8*3)+2(3*3)=114
answer: 114yd^2

Label the 3 distinct sides of the box. I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:
ab=54 in^2
ac=90 in^2
bc=60 in^2
Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c. Then the volume of the box is a*b*c.
Example: bc = 90, but c = 60/b. You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.
Continuing this procedure, I determined that a=9, b=6 and c=10. Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)
Answer:
The answer to your question is 24 cm³
Step-by-step explanation:
Data
Initial volume = 2/5
Additional volume = 42 cm³
Final volume = 4/7
the total volume of the glass = ?
Process
1.- Write a proportion to help you solve the problem
42 cm³ -------------------- 4/7 of the total
x ------------------- 7/7
2.- Solve the proportion
x = (7/7 x 42) / 4/7
3.- Simplification
x = 42 / 4/7
x = 168/7
x = 24 cm³
Sorry for the late response :<
Answer:
The unit rates would be comparable for both races. So, his speed is going to be the same for both races.
