Ahuman body that is performing light work generates about 650 btus of body heat per hour. if a room that is 10 ft × 12 ft × 9 ft is being painted by 3 people, how many btus per cubic foot do they produce in 2 hours? (to the nearest tenth)

1.5BTU/ft³( to nearest tenth)

Step-by-step explanation:

A human body generates 650BTus of heat per hour.

To get the amount of heat generated by a room with the dimension 10 ft × 12 ft × 9 ft

First we will find the volume of the room in cubic ft

Volume = length ×breadth × width

Volume = 10×12×9

Volume = 840ft³

This means 840ft³ produces 650Btu of heat by one body.

For 1ft³, amount of BTUs generated by the three person in an hour will be (640/840)BTU i.e 0.762BTU

Amount of heat in BTU/cubic feet generated in 2 hours will be

2 × 0.762BTU/ft³

= 1.524BTU/ft³

= 1.5BTU/ft³( to nearest tenth)

where is the diagram? shown below where? ?

step-by-step explanation:

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
