Answer:

Work done = 0 J

Step-by-step explanation:

work done= ∫ F. dr

                   = \int\limits^2_0 {x} \, dx +  \int\limits^2_2 {x} \, dx  + \int\limits^0_2 {x} \, dx  + \int\limits^0_0 {x} \, dx  +  \int\limits^0_0 {y} \, dy  + \int\limits^5_0 {y} \, dy  + \int\limits^5_5 {y} \, dy  + \int\limits^0_5 {y} \, dy + \int\limits^0_0 {z} \, dz  + \int\limits^1_0 {z} \, dz  + \int\limits^1_1 {z} \, dz  + \int\limits^0_1 {z} \, dz

Work done= x²/2 + y²/2 + z²/2

Applying integral limits for entire pathway

Work done= 2 + 0 -2 + 0 + 0+ 25/2 - 25/2 + 0 + 1/2 + 0 - 1/2

Work done = 0 J

What is the volume of this figure? <br> need help asap!!!!!
Marina CMI [18]

Answer: the answer should be 875 cubic feet

Step-by-step explanation:

The why is because we have to divide each rectangular prism into different pieces to use the volume formula. Doing this gives us 5*15*5 for the first part, the second part will be 20*5*5, the third square is 5*5*5.
