Answer:

This is not a regular polygon.

Regular polygons MUST be equilateral and equiangular.

This polygon is neither, so it is not a regular polygon.

A sculpture sits on a pedestal in the shape of a square prism. The side lengths of a base of the prism are 3 feet. The height of

german

Answer:

Total cost of covering the pedestal is $12.54.

Step-by-step explanation:

The pedestal is a square prism so top and bottom are of square shape.

Hence, we have here length = width

We know that the Total Surface Area of a Prism is:

$\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)$

Where l is length,

w is width and

h is height of prism

We know that here w = l = 3 feet

and h = 4 feet

Also, underside of pedestal is not to be covered.

The underside of pedestal is square type.

So,

$\text{Required Total Surface Area = } l\times w+ 2\times w \times h+2\times h \times l$

$\Rightarrow 3 \times 3 + 2 \times 3 \times 4 + 2 \times 3 \times 4\\\Rightarrow 9 + 24 + 24\\\Rightarrow 57\ ft^{2}$

Cost of cover per square foot = $ 0.22

Total cost of $57\ ft^{2}$ $\Rightarrow 0.22 \times 0.57 = \$12.54$
