The definition of density is given by:
D = m / V
Where,
m: mass
V: volume
The volume of the rectangular prism is given by:
V = (0.3) * (2.1) * (0.1)
V = 0.063 mi ^ 3
Substituting the values:
D = 0.07 / 0.063
D = 1.111111111 Kg / mi ^ 3
Round to the nearest tenth:
D = 1.1 Kg / mi ^ 3
Answer:
the density of the board is:
D = 1.1 Kg / mi ^ 3
Answer:
4. 23 in
Step-by-step explanation:
The tower is 1 1/4 feet high, then 8 inches are added. Well, we can't just add those two numbers. We have to change the units! Change everything to inches.
1 1/4 feet is equal to 12 inches + 3 inches = 15 inches, because a foot = 12 inches.
Add 8 inches to 15, and you get 23 inches.
<u>The answer is 4. 23 in. </u>
Oops wrong one man I’m sorry
A place value chart can help us in finding and comparing the place value of the digits in numbers through millions. The place value of a digit increases by ten times as we move left on the place value chart and decreases by ten times as we move right.
