Answer:
The surface area of the rectangular prism is 52 square feet (ft²), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Step-by-step explanation:
The given is,
A prism of
Let, h - height of the prism
w - Width of the prism
d - Depth of the prism
Step:1
From given,
h = 4 feet
w = 3 feet
d = 2 feet
Step:2
Formula to calculate the surface area of the rectangular prism is,
A=2(wd+hd+hw)
Substitute the values of w,d and h
= 2 [(3×2) + (4×2) + (4×3)]
= 2 (6+8+12)
= 2 × 26
= 52
A = 52 Square feet
Result:
Thus the surface area of the rectangular prism is 52 square feet (ft²), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Answer:
14.5 ft or 14 1/2 ft
Step-by-step explanation:
36in= 1 yard
9x36= 324in (I'm guessing this is the length)
324in (length) -150in (width)= 174in
12 in= 1 ft
174/12= 14 ft 6 in
6 inches is half a foot
14.5 ft or 14 1/2 ft
Y-2=-2.5(x-1)
Y-2=-2.5x+2.5
2.5x+y=4.5
<u>Given</u>:
Probability of student smoke,
P = 27.7%
= 0.277
Number of students,
n = 632
(i)
Here,
Number of students (n) = 60
then,
