An inverted pyramid is being filled with water at a constant rate of 25 cubic centimeters per second. The pyramid, at the top, has the shape of a square with sides of length 4 cm, and the height is 12 cm. Find the rate at which the water level is rising when the water level is 4 cm.

Step-by-step explanation:

We are given that

Side of base=4 cm

l=w=4 cm

Height,h=12 cm

We have to find the rate at which the water level rising when the water level is 4 cm.

Volume of pyramid=

Substitute the value

Differentiate w.r.t t

Substitute the values

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

answer: it is d
