Answer:
63m^2
Step-by-step explanation:
Find the area of each base
2.5(10)= 25
1.5(10) = 15
2(10) = 20
Add them together
20 + 15 + 25 = 60
Now find the area of the triangles at each side
2(1.5)(1/2) = 1.5
Since there are two triangles, multiply the area by 2
1.5(2) = 3
Add the areas together
60 + 3 = 63
There's your answer
The display after stacking of 6 layers of cube is 30 inches high.
Step-by-step explanation:
The volume of cubic box used by Abbey= 125 inch³
Total no of layer he has in display= 6
Height of the display-
We know that the volume of the cube is a³
Where a is the side of the cube
Hence to find the side of the cubic box we need to find the cube root of the volume i.e. ∛125
Hence the side of each cube is 5 inch. Since all the sides for cube are equal hence the height would also be 5 inch
The total height of the display would be 6*5= 30 inches
Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
