The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
Substituting:
The volume of the frustum is given by the formula:
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
<span>You can apply a rule of three.
If you travel a distance of 45 miles in one hour (equivalent to 60 minutes), then how many minutes (x) will it take 1 mile?
45 miles → 60 min
1 mile → x

Simplifying the fraction, dividing the numerator and denominator by 15
x=(60/15)/(45/15) min→x=4/3 min =1.333333333 min
approximately 1.33 min
Answer: It will take 4/3 min or 1.33 min to travel 1 mile</span>
