The volume of a Pyramid is 
V= \frac{1}{3} Bh
Big B means you have to multiply the base first so 16*16
to find the hight you can use the Pythagorean theorem 
the length of one of the sides is 16 so we have to divide that by 2 to get one of the legs for the Pythagorean theorem which is 8 and 17 is the hypotenuse.
Pug it in and it will look like this
8^{2} + b^2 = 17^2
square them to get
 64+b^2=289
subtract 64 from both sides to get 
b^2=225
then square root it to get the height
h=15
then plug that into your volume formula
V=  \frac{1}{3} 256*15
Add it up to get a volume of 1,280. Hope this helps Good luck :)

Answer:

The area of the rectangle is 0.0875  sq ft.

Step-by-step explanation:

Given that,

The length of the rectangle, L = 0.35 feet

The breadth of the rectangle, B = 1/4 feet

We need to find the area of the rectangle. The formula for the area of a rectangle is given by :

A = LB

Put all the values,

A=\dfrac{1}{4}\times 0.35\\\\A=0.0875\ ft^2

So, the area of the rectangle is 0.0875  sq feet.
