Answer:

See below.

Step-by-step explanation:

The volume is 1/3 * height * area of the base so we need the height and this area to find the volume. Note: if we join the point S to each of the vertices of the base we get 6 equilateral triangles so knowing the length of a side of the base we can find the area of the base.

The following lengths can be used:

XY and ST  We can get the area of the base knowing the length of XY and ST is the height.

VU and TW. From VU we can get the area of the base and the length of SW and from the length of TW and SW we can get the height.

TX and WX . From WX we can get the area of the base and the length of SX and from TX and SX we can find the height.

What is the value of the expression 3 squared times the quantity of 2 cubed + 4 all divided by 2 squared?
antoniya [11.8K]

Answer:

27

Step-by-step explanation:

Put this into numbers:

\frac{3^2*(2^3+4)}{2^2}

Use Order of Operations to simplify. First, you would do the stuff in parentheses which is:

2^3+4

Inside of those parentheses first simplify the exponents:

8 + 4

Now add

12

So the new equation is:

\frac{3^2*12}{2^2}

The next step is to simplify the exponents

\frac{9*12}{4}

Multiply out the top

\frac{108}{4}

Divide this
