The answer that would best tell the combination of shapes that could make a piano are: 3 cylinders and a rectangular prism
<h3>How to find the shape of a piano</h3>
The shape of a piano can be gotten from the way that the piano is built. A piano is known to have a shape that is like a chord, it also has the parts that is built like a rectangular prism.
In order to get the volume of the object, the different shapes that it has would be calculated individually using their formula.

its D my man go the answer sheet
Step-by-step explanation:
Answer:
41.5 units
Step-by-step explanation:
Given the data :
Month : J F M A M J J A S O N D
Inflow : 3 4 5 3 4 10 28 17 7 6 3 2
Outflow : 7 8 7 11 6 8 21 12 5 4 5 9
The unit of water in reservoir at the middle of August :
Initial unit = Unit of water at the start of the year = 50
Middle of August :
Inflow = 17 /2 = 8.5
Outflow = 12 /2 = 6
Unit of water at the middle of August :
Initial unit + Inflow - Outflow
Inflow till mid-August = (3+4+5+3+4+10+28+8.5) = 65.5
Outflow till mid-August = (7+8+7+11+6+8+21+6) = 74
50 + 65.5 - 74 = 41.5
Answer:
17
Step-by-step explanation:
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
