Suppose that 5 people sitting in an enclosed room are each generating about 500 btus of body heat per hour. if the room is 10ft x15ft x 10ft how many btus per cubic foot do they produce in 3 hours

the answer is 5 BTUs/ft^3

Step-by-step explanation:

first: 10x15x10= 1500 ft ^3

second: 500 BTUs x 5 people= 2500 BTUs by all five people

third: 2500 BTUs x 3 hrs= 7500 BTUs per 3 hrs

lastly: divide 7500 BTUs by 1500 ft ^3 to get 5 BTUs/ ft^3

the correct answer is 5 6 and 7

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
