Step-by-step explanation:The formula for volume of a square pyramid is A^2 * h/3 with A being base side length and h being height, so just plug in 3 for a and 5 for h, getting you (3)^2 * 5/3, then 9* (5/3) then 45/3 then 15
Answer:
Yes you count the squares to find the perimeter.
Answer:
10 + 20 = 30
Step-by-step explanation:
If you subtract 5 from 25 you get 20 which is the length distance from b to c. Let's do the same to 15, 15 - 5 = 10. So now let's add our given lengths: 10 + 20 = 30.
