Answer:
h = 9 cm
Step-by-step explanation:
A rectangular pyramid has a volume of 315 cm^3.
The base has a width of 15 cm and a length 7 cm.
Find the height h of the pyramid .
Vol = 1/3 (base area) h
where base area = 7 x 15 = 105 cm²
vol = 315 cm³
plugin values into the formula
315 = 1/3 (105) h
h = 315
(1/3 * 105)
h = 9 cm
Formula: V = 1/3bh
v = volume
b = base area
h = height
Find "b" or the base area
15 * 7 = 105
Solve for "h"
315 = 1/3(105)h
315 = 35h
9 = h
Therefore, the height is 9cm
Best of Luck!
