The surface area would be all those areas combined. The shape has been split up into 6 smaller quadrilaterals, so we can easily solve from there. The leftmost one would be 3*4 = 12. The two rectangles beside it can be combined: 4*7 = 28, the one beside it would be: 3*4 = 12, and the last column would be 4*7 = 28. The last thing you need to do is add them together: 12+28+12+28 = 80.
The surface area of the rectangular prism is 80
Answer:
The exact amount of empty space is
Step-by-step explanation:
we know that
To find out the exact amount of empty space, subtract the volume of the ball from the volume of the cylindrical can
step 1
Find the volume of teh ball
The volume of the sphere (ball) is given by
we have
---> the radius is half the diameter
substitute
step 2
Find the volume of the cylinder
The volume of the cylinder is given by
we have
---> the radius is half the diameter
substitute
step 3
Subtract the volumes
This is my work I hope it helps the equation is
y=-2/5x+13/5
