Answer:

The value of B (base\ area) = 27m^2

Step-by-step explanation:

Let's recall the the formula for volume of a pyramid.

Volume of a Pyramid = \frac{1}{3}\times B\times H}....equation (1)

where B=Base\ area (m^2) and H=height\ (m)

Now we have been given the values of V and H and have to find the value of B

Plugging the values of V and H in equation (1)

B=\frac{3\times V}{H}= \frac{3 \times 81}{9} = 27\ m^2

Now we can also check our previous results.

V = \frac{24\times 7}{3}=8 \times 7 =56\ m^3

So, our final answer is 27\ m^2
