Volume of the large pyramid = 1/3*(10)² *30= 1000 cm³
Height of the small pyramid that was cut = 30-15=15 cm
Volume of the small pyramid = 1/3*(5)²*15=125 cm³
Volume of the frustum = Volume large pyramid - volume small pyramid=
=1000-125=875 cm³
Answer is 875 cm³.

Step-by-step explanation:
I believe if i am getting your context right, the answer is 0.64
They got the 1.2 minutes by taking the total number of minutes (6) and dividing them by the number of laps run (5). So 6 divided by 5 gives you the 1.2.
To solve this problem, we have to find the perimeter of the shape.
we already know that two of the sides are 82m, all we need to do is find the circumference of the semicircles.
to find circumference, you multiply the diameter of a circle by pi. since we have two identical semicircles, we have one full circle. 66•3.14=207.24
207.24+82+82=371.24
the answer is 371.24m
