Answer:

V= 392 ft^3

Step-by-step explanation:

We know that the volume V of a pyramid is one-third the area of the base B times the height h.

If h= 8ft and areabase = 7ft x 7ft = 49 ft^2.

Then, the Volume V is:

V = areabase x height = 49 ft^2 x 8ft = 392 ft^3

So the solution is option D.

Answer:

Volume of pyramid is:

130\dfrac{2}{3}\ ft^3

Step-by-step explanation:

We know that the volume V of a pyramid is one-third the area of the base times the height h.

First we find the area of base let it be A.

A=7×7 ft²

A=49 ft²

Volume of pyramid=

\dfrac{1}{3}\times A\times h

Volume=

\dfrac{1}{3}\times 49\times 8

= \dfrac{392}{3}\\ \\=130\dfrac{2}{3}\ ft^3

Hence, Volume of pyramid is:

130\dfrac{2}{3}\ ft^3

Zigmanuir [339]

Answer:

x = 7

Step-by-step explanation:

The property of a parallelogram is the opposite sides are congruent, hence

AD = BC ← substitute values

5x + 3 = 38 ( subtract 3 from both sides )

5x = 35 ( divide both sides by 5 )

x = 7
