Answer:
Step-by-step explanation:
Find the volume first.
V= l * w * h
l = 2 cm
w = 3 cm
h = 1 cm
V = 2 * 3 * 1 = 6 cm^3
Density = mass / volume
Density = 420 grams / 6 cm^3
Density = 70 grams / cc^3
Kind of large. Check your givens.
Answer:
15
Step-by-step explanation:
5a - 10b = 45
5a - (10×3) = 45

a = 15
Answer: three pieces.
The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.
Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.
1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.
