Total room in the 2 suitcases is 33 ft³
Step-by-step explanation:
- Step 1: To find the total room in the suitcases, find volume of the suitcases, given by V = length × width × height
⇒ Volume of 1st suitcase = 3 × 2 × 4 = 24 ft³
⇒ Volume of 2nd suitcase = 3 × 1 × 3 = 9 ft³
∴ Total room in Sandra's suitcases = 24 + 9 = 33 ft³
Answer:
A square has all sides congruent. SIDE A, B, C and D would be congruent in size to one another, and the angles would also be equal to one another. However, most any polygon can be drawn with all sides and angles equal. For instance, an equilateral triangle has all sides and all angles equal, and that is the definition of a polygon. Polygons with more sides are described as "regular" e.g., a stop sign or an equilateral octagon is also a shape that has all sides congruent. A rectangle, however, would not, since only two sides would be congruent to one another.

Serena had 7 4/9 yd of tape.
She used 2 1/9 yd.
How much tape does she have left?
7 4/9
- 2 1/9
--------------
Since both fractions have the same denominator, and since the lower fraction is smaller than the upper fraction, you can subtract the fractions by subtracting the numerators and using the same denominator. Then also subtract the whole numbers.
7 4/9
- 2 1/9
--------------
5 3/9
The difference is 5 3/9.
3/9 can be reduced since both 3 and 9 are divisible by 3, so we divide both 3 and 9 by 3 to get 1/3.
Answer: 5 1/3 yards
To verify this, we can simply find the area of the triangle using the well-known formula
, where
and
are the base and height, respectively of the triangular region
. We have
, so the area is
, as expected.
