Answer:
5229 mm³
Step-by-step explanation:
Volume of square pyramid

b = base length = 25 mm
H = height
We have to find 'H' using Pythagorean theorem,
slant height (hypotenuse) = 28 mm
leg₁ = base length ÷ 2 = 25÷2 = 12.5
leg₂ = H
H² + (12.5)² = 28²
H² = 784 - 156.25
= 627.75

H = 25.01 mm

= 5229 mm³

Answer:
length is 3 and width is 8

There are approximately 4 weeks per month.
Mr. Gleason will take home 1100 x 4 weeks = $4,400 per month.
The total budget - his take home pay is the amount his wife will need to make:
5,600 - 4,400 = $1,200
Now divide the total amount she needs to make by how much she brings home per hour:
1,200 / 10 = 120
She needs to work 120 hours per month.
The answer is D.
The lower bound is 7177.5
