A sandbox 12ft. By 14 ft. requires that the sand be spread to a depth of 6 in. How many cubic feet of sand are needed?
2 answers:
Answer:
84 ft²
Step-by-step explanation:
Solve for Volume. Volume of a box is:
V = Length (base) x Width (base) x Height (of rectangular prism/square)
Change each measurement to have the same measurement (ft -> in, or vice versa).
Note that 1 ft = 12 in.
6 in = 1/2 ft, because 6/12 = 1/2
Length = 12 ft
Width = 14 ft
Height = 1/2 ft
Solve. Plug in the corresponding number to the corresponding words.
V = 12 x 14 x 1/2
Simplify. Solve.
V = 12 x (14 x 1/2)
V = 12 x (14/2)
V = 12 x 7
V = 84
84 ft² is your answer.

3) 39cm^2
Answer:
x={-5,-6}
Step-by-step explanation:
x²+11x+30=0
x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)
x(x+5)+6(x+5)=0
(x+5)(x+6)=0
so
x+5=0
x+6=0
therefore
x=-5
x=-6
