Answer:
729 in³
Step-by-step explanation:
Fill in the given numbers in the formula and solve for V.
... A = 6V^(2/3) . . . . . . the given formula
... 486 = 6V^(2/3) . . . . with the given area filled in
... 81 = V^(2/3) . . . . . . . divide by 6
... 81^(3/2) = V . . . . . . . raise to the 3/2 power. (2/3)·(3/2) = 1, so we have V on the right
... 729 = V . . . . in³
_____
You may have noticed that (81 in²)^(3/2) becomes 729 in³. The exponent operations work on the units, too.
Answer:
208 square inches
Step-by-step explanation:
2(8 X 4) + 2(6 X 4) + 2(8 X 6)
64 + 48 + 96 = 208 square inches

-3/4 - 2/3 ÷ (-4/5)
= -3/4 - [2/3 ÷ (-4/5)]
{switch the numerator and denominator when changing from ÷ to ×, or × to ÷}
= -3/4 - [2/3 × (-5/4)]
{numerator × numerator, and denominator × denominator}
= -3/4 - [-10/12]
= -3/4 + 10/12
= -9/12 + 10/12
= 1/12
5.
-2 2/5 + (-2 4/5) × 4/7
= -2 2/5 - (2 4/5 × 4/7)
= -12/5 - (14/5 × 4/7)
= -12/5 - (56/35)
{Simplify fraction to make denominators same}
= -12/5 - (8/5)
= -20/5
= -4/1
= -4
6.
-(-3/5) - 1 3/7 ÷ (-5/14)
{Negative signs cancelled out, fractions compounded}
= 3/5 - 10/7 ÷ (-5/14)
{Switch numerator and denominator when switch from ÷ to ×}
= 3/5 - [10/7 × (-14/5)]
= 3/5 - [-140/35]
= 3/5 + 20/5
= 23/5
{Simplify fraction}
= 4 3/5
