1 imperial foot has approximately 30.48 metric centimeters, and for one present we need 3 ft, or namely 3(30.48) cm, how many can we get from 102 cm? 102 ÷ 3(30.48) ≈ 1.1155, so barely just one present.
First, multiply 15 times 2, which is 30.
Then, multiply 0.5 times 0.2, which is 0.1.
Add them together!30 + 0.1 = 30.1 :)
Answer:
use the formula of centroid that is
= x1+x2+x3/3
