Hello!
<h3><em><u>Answer</u></em></h3><h3 />
The surface area of the cube is 150 .
<h3><em><u>Explanation</u></em></h3>
A = 6
A = 6
A = 6 × 25
A = 150
Answer:
I think the answer is 39x, 13y
Step-by-step explanation:
point : extra points
1 : 3
y : 39
y= 39÷3
y= 13
First, we need to calculate the surface area of the prism, to know how much space we need to cover. An important fact to keep in mind is that with a cuboid, there are three pairs of identical faces. This means that there are:
Two faces with a surface area of 2×1=2ft²
Two faces with a surface area of 3×2=6ft²
and two faces with a surface area of 1×3=3ft²
So, the total surface area of the shape is:
2(2)+2(6)=2(3)
=4+12+6
=22ft²
Knowing that each tile costs 1ft², then Marita will need 22÷1=22 tiles. Therefore, the total cost of tiling the whole prism is 22×0.45= $9.90
<span>So we know the area A=595cm^2 of the square piece of fabric and we want to calculate one side to the nearest tenth. So the formula for the area of a square is A=a^2 so we simply need to take the square root of the area to get the lenght of one side: a=sqrt A=24.39262 cm. Rounded to the nearest tenth: a= 24.4 cm. So the correct answer is C. 24.4 cm</span>
