Part A.
Ashwin had a 4-cm cube.
volume of cube = side^3
volume = (4 cm)^3 = 64 cm^3
Ashwin has 64 small cubes.
We need to find the volumes of all prisms in Part A. Only prisms with at most 64 cm^3 volume can be the answer.
A. v = 2 * 4 * 7 = 28
B. v = 4 * 5 * 6 = 120
C. v = 5 * 5 * 4 = 100
D. v = 4 * 7 * 5 = 140
E. v = 3 * 5 * 4 = 60
Part A. answer: A, E
Part B.
Dora had a 5-cm cube.
volume of cube = side^3
volume = (5 cm)^3 = 125 cm^3
Dora has 125 small cubes.
We need to find the volumes of all prisms in Part B. Only prisms with at most 125 cm^3 volume can be the answer.
A. v = 3 * 3 * 8 = 72
B. v = 3 * 4 * 5 = 60
C. v = 6 * 6 * 4 = 144
D. v = 5 * 8 * 4 = 160
E. v = 3 * 5 * 4 = 60
Part B. answer: A, B, E
Answer: 14 grams
Step-by-step explanation:
It took 4 balloons to make a duck that weighs 56 grams to float. With one balloon, the number of grams that will float will be 56 grams divided by 4. This will be:
= 56 grams ÷ 4
= 14 grams
Answer:
Step-by-step explanation:
we know that
The circumference of a circle is equal to
we have
Convert to an improper fraction
substitute
Answer
8.66025.....or 9
Step-by-step explanation:
Alright so in the bottom we have 8. If we divide them by 2 it = 4. The answer has to do with The Pythagorean theorem. So <em>a²+b²=c².</em> a=8, b=3. e=?.
8²+3²=e².
64+9= √75
√75 is 8.66.....or 9.
