Answer:
Step-by-step explanation:
We would section the bread into a cuboid at the bottom and a semi cylinder at the top.
Considering the bottom, the formula for determining the volume of a cuboid is expressed as
Volume = length × width × height
Therefore,
Volume = 20 × 11 × 6 = 1320 cm³
Considering the semi cylinder,
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder
h represents the height of the cylinder.
π = 3.14
Looking at the diagram,
Height = 20 cm
Diameter = 11 cm
Radius = diameter/2 = 11/2 = 5.5 cm
Since it is a semi cylinder, then
Volume = 1/2 × 3.14 × 5.5² × 20 = 949.85 cm³
Therefore, volume of this loaf of bread is
1320 + 949.85 = 2269.85 cm³
