Answer:
Density of the rock is 2.7 grams per cubic centimeter.
Step-by-step explanation:
Jeremy wants to know the density of a rock in grams per cubic centimeter.
The rock has mass M = 1.08 kilograms
Since 1 kilogram = 1000 grams
Therefore 1.08 kilograms = 1.08×1000 = 1080 grams
Volume of the rock is given as V = 400 cubic centimeters
Now we know the formula of Density =
Therefore density of the rock is 2.7 grams per cubic centimeter.

2) √32 +3√18-2√50
= √16*2 +3√9*2-2√25*2
= 4√2 + 3(3√2)-2(5√2)
= 4√2 + 9√2-10√2
= 13√2-10√2
= 3√2
3) 1000 ⅔×64⅙
4) 3/4+√2
5) 2√3×√18
= 2√3×√9*2
= 2√3×3√2
= (2*3)(√3*√2)
= 6√6
6) 12/3+√3
= 4+√3
7) √1000—2√40
= 10 -2 (√4*10)
= 10-2(2√10)
= 10 - 4√10
