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:
Step-by-step explanation:
First you will need to change both of the numbers into improper fractions:
56/1 ÷ 7/2
Then do keep change flip. What that means is keep the first fraction the same, change the division symbol into a multiplication symbol, and flip the second fraction:
56/1 x 2/7
Then just multiply the two numerators by each other and the two denominators by each other:
56 x 2 = 112
7 x 1 = 7
112/7 would be the answer.
