Step-by-step explanation:
The difference of two cubes formula is given as:

9514 1404 393
Answer:
12.9 square yards
Step-by-step explanation:
The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...
A = 1/2bh
A = 1/2(3 yd)(2 yd) = 3 yd²
The base area is computed using the same formula and the given height:
A = 1/2(3 yd)(2.6 yd) = 3.9 yd²
Then the total surface area is that of the base and the three faces:
SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area

Answer:
2.5
Step-by-step explanation:
t = 0.25
Substitute d with 100
t = 0.25 x (
)
A number to the half power is equal to the square root of a number.
Square root of 100 is 10: 
t = 0.25*10
t = 2.5
Hope this helps :)
