Answer:
2). Volume = 14400 feet³
3). Volume = 157.5 ft³
Step-by-step explanation:
Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.
2). In this part of the question solid given is in the shape of an rectangular pyramid.
Volume of this oblique pyramid = 
Here 'B' = area of the base
h = height of the pyramid
Volume = 
= 14400 cubic feet
4). Volume of a triangular cone = (Area of the triangular base)×(height)
= ![[\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%28%5Ctext%7Bheight%7D%29%5D%5Ctimes%20%7B%5Ctext%7Bheight%20of%20the%20prism%7D%7D)
= 
= 157.5 ft³

A regular polygon of "n" sides has "n" Lines of Symmetry
so a regular 32 sided polygon has 32 lines of symmetry
Answer:
About 4 hours.
Step-by-step explanation:
Let's set up a proportion and cross multiply.
Cross multiply.
120 = 28x
Divide by 28 on both sides.
= 4.28571428571
Round this to the nearest whole number, which is just 4. The answer is about 4 hours.
A balanced and proportionate likeness observed in two sides of an item is characterized as symmetry. The shape can be completed as shown below.
<h3>What is symmetry?</h3>
A balanced and proportionate likeness observed in two sides of an item is characterized as symmetry. It signifies that one side is a mirror image of the other. The line of symmetry is the imaginary line or axis along which you can fold a figure to produce the symmetrical halves.
The shape can be completed as shown below, so that the complete shape is symmetrical about the given axis.
