A driveway is 81 ft. long, 6 ft. wide and 4 inches deep. How many cubic feet of concrete will be required for the driveway
Answers
Answer 1
Answer:
The equation for volume is v = length x width x height. We are given all of these, however one of the measurements is in different units than the others, so we need to convert the units before we do our multiplication...
4 inches x 1 ft / 12 in = 4/12 = 1/3 ft
Now we can multiply our equation...
v = length x width x height v = 81 x 6 x 1/3 v = 486/3 v = 162 cubic feet
Answer 2
Answer:
First the units must all be in feet. 4 inches has to be converted to feet 4 inches x 1ft/12 inches = 4/12 ft = 1/3 ft
The driveway is a rectangular prism. Area = length x width x height Area = 81 ft x 6 ft x 1/3 ft = 162 cubic feet

5) A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of the base of the speaker is 11 square inches. What is the volume of the speaker in cubic inches?
Answers
volume of the speaker= 22 cubic inches
Step-by-step explanation:
The formula to find this question is
V= 1/3 BH
WHERE H =6 INCHES
Area of base = 11 square inches
therefore,
v= 1/3 (11) (6)
volume of the speaker= 22 cubic inches

Three. Angles in a quadrilateral measure 31 83 and 146 what is the measure of the fourth angle?A 82 B 97 C 100 D 112
Answers
The answer is C. For any quadrilateral, the sum of all the angles must be 360. So, you add the three angles that you know, then subtract that number from 360 to get the answer.
