Answer: I believe the answer is A.
Explanation: hope this helps
8 right? Don’t mind this it’s just bc I have to have 29 characters lol.
The answer is 10 x 62. He has 62 across, and 10 vertically. To find how many total he needs, you have to multiply both together. I hope this helps!
Answer:
23,064
Step-by-step explanation:
multiply two numbers
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)
