36 ft 24 ft
18 ft 12 ft
10 ft 6 ft
12 ft 5 ft

Answers

It would be 18 ft by 12 ft because P=L+L+W+W, which 18+18 is 36 and 12plus 12 is 24. 24 and 36 ft combined is 60 ft.

The surface area of a cube is 294 cm2. Which statements are true about the same cube measured in square millimeters? Choose all answers that are correct. A. The number representing the surface area would decrease. B. The number representing the surface area would increase. C. The actual surface area would decrease. D. The actual surface area would increase. E. The actual surface area would stay the same.

Answers

To check whether the statements are correct, we need to convert cm to mm.

surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a

1 cm = 10 mm
7 cm = 70 mm

Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²

B. The number representing the surface area would increase.
E. The actual surface area would stay the same.

the lengths of two sides of a triangle are 3 centimeters and five centimeters write an inequality to represent the range of values for the third side

Answers

There exists one simple and interesting conclusion for triangle, that is the sum of any two sides's length are longer than the other side and the difference between the length of any two sides is smaller than the other side, If, we use L to denote the length of the third side, we can conclude that: 5-3<L<5+3
