Answer:
32 books.
Step-by-step explanation:
What do we know?
As Olive continues this pattern, this will involve multiplication.
4 books per month and 8 months.
4*8=32 books.
So, Olive will read 32 books within 8 months.
1) We calculate the volume of a metal bar (without the hole).
volume=area of hexagon x length
area of hexagon=(3√3 Side²)/2=(3√3(60 cm)²) / 2=9353.07 cm²
9353.07 cm²=9353.07 cm²(1 m² / 10000 cm²)=0.935 m²
Volume=(0.935 m²)(2 m)=1.871 m³
2) we calculate the volume of the parallelepiped
Volume of a parallelepiped= area of the section x length
area of the section=side²=(40 cm)²=1600 cm²
1600 cm²=(1600 cm²)(1 m² / 10000 cm²=0.16 m²
Volume of a parallelepiped=(0.16 m²)(2 m)=0.32 m³
3) we calculate the volume of a metal hollow bar:
volume of a metal hollow bar=volume of a metal bar - volume of a parallelepiped
Volume of a metal hollow bar=1.871 m³ - 0.32 m³=1.551 m³
4) we calculate the mass of the metal bar
density=mass/ volume ⇒ mass=density *volume
Data:
density=8.10³ kg/m³
volume=1.551 m³
mass=(8x10³ Kg/m³ )12. * (1.551 m³)=12.408x10³ Kg
answer: The mas of the metal bar is 12.408x10³ kg or 12408 kg
Answer:
The surface area applies to how much space a SOLID objects occupies while volume is the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains, so volume can be anything.
Step-by-step explanation:

Answer:
5.5 inches
Step-by-step explanation:
1) the formula to find the area of a square is l^2= area and l=length
in this case we already know the area but not the length
so we have to find the square root of 30 as the opposite operation needs to be used to find the missing number
so
√30= 5.47
5.47 rounded= 5.5
the length of one side is 5.5 in
