Answer 1

Answer:

• Volume = 1.3m³

Step-by-step explanation:

The height of the pyramid (h) = 3.6m

The perimeter of the base = 4.1m

Volume of a pyramid = ?

Formula:-

$\boxed{\sf Volume =\cfrac{1}{3} \: a^2h}$

So,

Perimeter = 4a

$\sf 4.1=4a$

$\sf a=1.025$

Now, let's put the value of a in the formula:-

$\sf V=\cfrac{1}{3} \:(1.025)^{2} (3.6)$

$\sf 1.26075m^2$

$\sf \thickapprox 1.3m^3$

Therefore, the volume of the pyramid is 1.3m³.
