140.4 since the sides are equal . Iguess . I did not calculate or anything but mentally
Answer:
486 yd^2
Step-by-step explanation:
Surface area is just finding the area of each face in a figure and adding it all up.
For the surface area of a cube, use this formula:
(a^2) 6
(a is the side length) a^2 is the area of one face of a cube, then multiply it by 6 since there are 6 faces on a cube.
Use formula with given dimensions:
(9^2) 6 = 486
Surface area is measured in square yards
(yards in this case)
Therefore, the surface area of the cube is 486 yd^2
Hope this helps!
You are given
the surface area of the cube which is 96cm2. You are asked to find the length
of one side and its volume. Note that the surface area of the cube is equal to
6 times the square root of s (the side of the cube) and the volume is the cube
root of s. So,
SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
<u>s = 4cm,
this is the length of one side.</u>
V = s^3
V = (4)^3
<u>V = 64cm3,
this is the volume of the cube.</u>
So first you need to find the area of the building site which is:
length x width
39.5m x 32.5m
= 1283.75
We know that one square meter costs 185.50 euros.
1 = 185.50 euros
1283.75 = <u>238135.625 euros</u>
I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are <u>238134.86 and 238135.86.</u>
sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!
