62 1/3long by 19ft wide &will be2/3 foot thick how many cubic yards of coement willbe needed?

Answer 1

volume = length * width * depth
v = 62 1/3 ft * 19 ft * 2/3 ft
v = 789 5/9 ft^3

To convert cubic feet into cubic yards, you need to divide by the cube of the number of feet in a yard (3^3 = 27).

789 5/9 ft^3 =
(789 5/9) / 27 yd^3 =
29 59/243 yd^3 =
about 29.243 yd^3

Answer 2

(i'm utilising * for multiplication, and / for branch) There are 21 * 18 * 9 cubic ft in the room. there's one million cubic backyard in the room for each 27 cubic ft in the room. "for each" ability you divide. as a result, there are 21 * 18 * 9 / 27 cubic yards in the room. 21 * 18 * 9 / 27 = 126. yet in a different thank you to do it: First convert the ft to yards, then multiply them jointly. There are 3 ft in a backyard, so the respond is: 21/3 * 18/3 * 9/3 = 126. Why those 2 techniques are mathematically equivalent: because of the fact it is not substantial what order you multiply or divide in, you need to use algebra to alter this to: (21*18*9) / (3*3*3) 21*18*9 is the form of cubic ft in the room: 3402. 3*3*3 is how many cubic ft are in one million cubic backyard: 27. 3402 cubic ft / 27 cubic ft according to cubic backyard = 126 cubic yards. a splash extra stepped forward: observe, you are able to cope with the instruments like numbers. one million * [cubic yards] = 27 * [cubic ft] as a result, one million = 27 * [cubic ft] / [cubic yards] 3402 * [cubic ft] / one million = 3402 * [cubic ft] / (27 * [cubic ft] / [cubic yards]) 3402 * [cubic ft] * [cubic yards] / (27 * [cubic ft]) = 3402 * [cubic yards] / 27 = 126 * [cubic yards]

Answer 3

basically, the question ask for the volume in yard^3 instead of ft^3

1yard = 3ft

62 1/3ft = 187/9 yard
19ft = 19/3 yard
2/3 ft = 2/9 yard

V = 287/9 * 19/3 * 2/9 = 29.24 yard^3
