Q. Question 61 ptsA square pyramid has a volume of 484cm3 and a height of 12cm. Find the length.11cm40.3cm121cm
Identify Formula: Identify the formula for the volume of a square pyramid.Volume = (31)×base area×heightHere, the base area is the area of the square base, which can be calculated as side length squared (s2).So, Volume = (31)×s2×heightGiven: Volume = 484cm3, height = 12cmWe need to find the side length (s).
Substitute and Solve: Substitute the given values into the volume formula and solve for s2. 484cm3=(31)⋅s2⋅12cmTo isolate s2, multiply both sides by 3 and divide by 12. (3⋅484cm3)/12=s2
Calculate s2: Calculate the value of s2. s2=123×484 cm3 s2=121452 cm3 s2=121 cm2
Find Side Length: Find the side length s by taking the square root of s2.s=121cm2s=11cm
