This isn't as hard as it looks.
The ratio is 1 to 12.
You just have to multiply the model value by 12.
12 x 5.4 = 64.8 feet. Now, the answer has to be in yards, so divide by 3.
64.8 div 3 = 21.6 feet.
Answer:
3,216 cm²
Step-by-step explanation:
The question is asking the surface area of a rectangular prism with the given dimension. That area is the sum of the areas of the 6 faces of the prism. Since opposite faces have the same area, we only need to compute 3 areas, then double the sum of those:
S = 2(LW +LH +WH)
This can be made a little easier to compute by some factoring:
S = 2(LW +H(L +W))
It does not matter which dimensions are designated length (L), width (W), or height (H).
__
S = 2((24 cm)(54 cm) +(4 cm)(24 cm +54 cm))
= 2(1296 +4(78)) cm² = 2(1608) cm²
S = 3216 cm²
The surface area of Emma's rectangular box is 3216 square centimeters.
Personally if I would of put it in a fraction it be 2/10
Numbers 27 and 81 have 27 as common factor which is equal to 3^3. Noting that we can put 27 before brackets write it in form 3^3 and that third root and cube will trim.

-5 means that graph is shifted 5 to down.
-3 means it is shifted to right by -3
3 and ∛ represent scaling of graph which can be seen and tested once you draw it. It is harder to explain it with words.
ANSWER
B.

EXPLANATION
The given expression is

First factor 7 to get,

Write the expression in the parenthesis as difference of two squares:

Recall that:

We apply this to our expression to get:
