Answer:
Total surface area of the prism =145.32 Square centimeters
Step-by-step explanation:
The given figure is a rectangular prism with the given dimensions of :
length(L)= 10.3 cm
Width(W)=2.2 cm
Height(H)=4 cm
Total surface area of the rectangular prism is:
Total surface area of the prism is 145.32 Square centimeters
If the original side length is "s" and the original slant height is "h", the original surface area is
.. S = (base area) +(lateral area)
.. S = s² +(1/2)*(4s)*h
.. S = s(s +2h)
Now, if we make these replacements: s ⇒ 3s, h ⇒ h/5, we have
.. S' = (3s)(3s +2h/5)
.. S' = 9s² +(6/5)s*h . . . . . . . the formula for the modified area (in terms of original dimensions)
_____
Of course, in terms of the modified dimensions, the formula is the same:
.. S' = s'(s' +2h')
The answer is to your question is 100:1
Answer:
x = 1/2
Step-by-step explanation:
x^3 = 1/8
Take the cube root of each side
x^3 ^ (1/3) = (1/8)^ (1/3)
Rewriting 8 as 2^3
x^3 ^ (1/3) = (1/2^3)^ (1/3)
x = 1/2
1. X+2=3x-4
6=2x
x= 3
2. y= 8-x
8-x = 3x+4
4= 4x
X= 1
3. -2x +3(2x+7)=9
-2x + 6x + 21 = 9
4x = -12
x= -3
