Answer:

75cm^2

Step-by-step explanation:

When you say a rectangular prism, it means it has the base has 4 sides of which opposite sides are equal as a rectangle. This sides substends so we have a total of 6 surfaces in this prism.

This 6 surfaces has 3 surface area the same.

The surface area = sum of area of all faces.

325= 50 + 50 + 37.5 + 37.5 + 2x; where X is the area of the surface unknown.

325= 100+ 75 + 2x

325-175= 150

150= 2x

X= 150/ 2 = 75 cm^2

A lawn mower is pushed a distance of 100 ft. Along a horizontal path by a constant force of 60 lbs. Yhe handle of the lawn mower
olga2289 [7]
For this case we have the following equation:
 w = || F || • || PQ || costheta
 Where,
 || F ||: force vector module
 || PQ ||: distance module
 costheta: cosine of the angle between the force vector and the distance vector.
 Substituting values:
 w = (60) * (100) * (cos (45))
 w = 4242.640687 lb.ft
 Answer:
 
The work done pushing the lawn mower is: 
 w = 4242.640687 lb.ft
