What's the total surface area of a covered box with a length of 4 ft, a width of 3 ft, and a height of 6 ft?
1 answer:
Answer: 108 square feet
===============================================
Work Shown:
L = 4 = length
W = 3 = width
H = 6 = height
SA = surface area of the box
SA = 2*(LW + LH + WH)
SA = 2*(4*3 + 4*6 + 3*6)
SA = 108

3/2(1/2x + 12) =1/2(1/3x + 14) – 3
3/4x + 9 = 1/6x + 7 – 3
3/4x + 9 = 1/6x + 4
3/4x + 9 = 1/6x + 4
14/24x = -5
x = -5*24/14 = -60/7

Answer:
got what?
Step-by-step explanation:
12^2 + 9^2 = x^2
144 + 81 = x^2
225 = x^2
√225 = √x^2
x = 15
