It is 76o F at the 6,000-foot level of a mountain and 49o F at the 12,000-foot level of the mountain. Write a linear equation to find the temperature "T" at an elevation "x" on the mountain, where "x" is in thousand feet. WILL GIVE BRAINLIEST

15 write your number

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
