Iwill give brainliest find height of each pyramid: triangular pyramid: volume 56 cubic centimeters, base edge 8 centimeters, base height 7 centimeters

V=1/3Bh

B=1/2bh

b=8

h1=7

h2=?

V=1/3(1/2bh1)h2

56 = 1/3(1/2 x 8 x 7)h2

56 = 1/3(28)h2

56 = 9.33h2

56/9.33 = 9.33h2/9.33

6=h2

Check:

V=1/3(1/2bh1)h2

56 = 1/3 (1/2 x 8 x 7) 6

56 = 1/3 (28) 6

56 = (1/3 x 28 x 6)

56 = 56

So, the height of the pyramid is 6.

Hope this helped! Have a great rest of your day! :)
