The surface area is 169.65ft^2
Syes everything is same according to base
Question will be modify
I translate the task in english "Silvia and Rebecca buy on line 10 cubes of styrofoam to coated fabric.The size of each cube contained in the website are 150x150x150mm.May be sufficient 2m^2 of cloth?You why?No why?"
We need to find the area of full surface of cube. The formula is 6 * A^2.
150mm=15sm=0,15m.
0.15^2=0.0225 m^2 of fabric for one side.
Cube have 6 sides.
6*0.0225=0.135 m^2 of fabric for one cube.
And we need to cover 10 cubes, so we must to multiply 0.135 by 10.
10*0.135=1.35 m^2.
Answer: it's enough of 2 m^2
Answer:
90 degrees
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

Step-by-step explanation:
C = 14.85
S = 16.90
c = 5.99
d = 6.99
3) 0.2(3C+2d)
round C to 15 and d to 7 cause that's about right
No cause that's about 12 and 5 is way too low.
So actually work it out now
0.2(3(14.85)+2(6.99))
0.2(44.55+13.98)
0.2(58.53)
11.706 but in terms of money it would be 11.71
4) 5S+5C+5c+5d
C is about 15, S is about 17, c is about 6, d is about 7
that is about 225
That seems reasonable.
(The real total though is 2223.65)
5) t=1.39
14.85+1.39x=20
Lets round those numbers again to make it easy to work with
15+1.5x=20
1.5x=5
x=3.33333
No, you cannot add 4 toppings and still pay $20
He over estimated
1.39x=5.15
x=3.70503597
you can get 3.
