Without computing, select all of the expressions that have the same value as 81. (37 + 59).
A. 81. (59 +37)
Answer:
0.25 cents
Step-by-step explanation:
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.
