Considering the provided information in the given question we have,
- A gift box is in the shape of a cube.
- Length of each edge = 4.5 in
We need to find the volume of the gift box. Since it is in the shape of a cube, we wee need to apply the formula of the volume of a cube. We know that,
→ Volume of cube = l × l × l
→ Volume of cube = 4.5 in × 4.5 in × 4.5 in
→ Volume of cube = ![\sf 91.125 \: in^3](https://tex.z-dn.net/?f=%20%5Csf%2091.125%20%5C%3A%20in%5E3%20%20)
Therefore, volume of the gift box is
.
Answer:
9.12 m^2
Step-by-step explanation:
14*.305=4.27 m
7*.305= 2.135m
multiplied together is 9.12 m^2
The average speed of the student for his entire walk is equal to 1.5 m/s. Therefore, option (b) is correct.
What is the average speed?
The average speed of a body is calculated as the total distance traveled in a fixed interval of time. The average speed can be determined by dividing the total distance traveled by a body by the total time.
The average velocity is a single value if the object moves uniformly. Speed is a scalar quantity, it has no specified direction. The average speed has the S.I. unit the same as velocity i.e. m/s.
Given the distance covered by a student in first 80 sec = 100m
After stooping for 30sec again cover a distance of 200m in 90sec.
The total distance traveled by the student = 100 + 200 = 300m
The time taken by student to cover distance = 80 + 30 +90 = 200 sec
The average speed of the student = total distance/ total time taken
= 300/200 = 1.5 m/s
Therefore, the average speed of the student is equal to 1.5m/s.
