A rectangular prism has the following dimensions. length: 18 inches width: 1 foot height: 14 inches If all the dimensions of thi
s prism are tripled, what will be the surface area of the new figure?
3,816 in.2
7,632 in.2
27,216 in.2
11,448 in.2

Answer:
11,448 in.2
Step-by-step explanation:
Answer:
11,448 in²
Step-by-step explanation:
The area can be computed from ...
... A = 2(LW +H(L+W))
For the given prism, the area will be ...
... A = 2(18·12 +14(18+12)) = 2(216 +420) = 1272 . . . . in²
The area of a similar figure with dimensions 3 times as long will be 3² times as much. The area of the new figure is ...
... A = 3²×(1272 in²) = 11,448 in²

I think that x may equal to -3. Because the sum of a triangle is always 180. 55+54=109 and 180-109=71 and -3+74=71
Hey there!
The quotient of 8595 ÷ 24 would be 358.125.

Answer:
C: H <u>> </u> 60
Step-by-step explanation:
H is 60 in or taller, underlined indicates that it's also 60 in, not just above it.
think the answer is
x=6+sqrt0/2 x=6-sqrt0/2 both equaling into 3.
But I might be wrong.
Answer:
i= -6
Step-by-step explanation:
-5i-15=15
if we use inverse operation here, it would be -5i=30, so i= -6
