The oblique pyramid has a square base. What is the volume of the pyramid? 2.5cm3 5cm3 6cm3 7.5cm3
Reil [10]

Answer:

<h2>V = 5 cm³</h2>

Step-by-step explanation:

The formula of a volume of a pyramid:

V=\dfrac{1}{3}BH

<em>B</em><em> - base area</em>

<em>H</em><em> - height</em>

<em />

In the base we have a square withe side <em>s = 2cm</em>

The formula of an area of a square with side <em>s</em>:

A=s^2

Substitute:

A=2^2=4\ cm^2

The height <em>H = 3.75 cm</em>.

Calculate the volume:

V=\dfrac{1}{3}(4)(3.75)=\dfrac{15}{3}=5\ cm^3

the volume of pyramid shown above is 147.97units and the height is is 9.6 units find the length of one edge of the square base
AlekseyPX
<span>The formula fro the volume of a pyramid with a square base is:
Volume = L * L * H / 3
L * L * 9.6 / 3 = 147.97
L * L = (3 * 147.97) / 9.6
L * L = 46.24
Let's take the square root of both sides.
L = sqrt(46.24) = 6.8
The length of one edge of the square base is 6.8 units.</span>

Solving Exponential Equations (lacking a common base)<br> 31^d=38
Bond [772]

Answer:

d = log 38/log31

d = 1.06

Step-by-step explanation:

31 ^ d = 38

Take log of both sides since the exponential equation have different base (always)

d log 31 = log 38

d = log 38 / log 31

d = 1.58 / 1.491

d = 1.06.

We can actually check to see if this is correct.

Substituting d = 1.06

31^ 1.06 = 38.092

(You see, that's approximately correct)

Keep learning, maths is fun!
