Answer:
GCF= 1
LCM= 1680
Step-by-step explanation:
GCF= Find the prime factorization of 21, 21 = 3 x 7
Find the prime factorization of 80, 80 = 2 x 2 x 2 x 2 x 5
Then multiply the prime factors both numbers have in common
LCM= multiply the two numbers together and ignore all negative signs
8 x 5 x 4 = 160m^3
to find the volume of a cube its V= W x H x L
Answer:
18.84 cm
Step-by-step explanation:
P = 2 × pi × r
= 2 × 3.14 × 3cm
= 6cm × 3.14
