4. What is 888 minutes in hours and minutes.
5. If the area of square is 49 square cm then find its Perimeter.
6. If Finishing time is 10.15 P.M. and Time duration is 6 hours then find its
Starting time.
7. What is the length of edge of cube of volume 1000 cubic cm.​

Answer 1

Answer:

3. perimeter of the square is 40 cm

so, side of the square is 40/4 cm=10 cm

4. 888minutes=888÷60 hour

=14 hours 48 minutes

5. area of a square is 49 sq cm

side of the square =√49 cm=7 cm

it's perimeter=4×7cm=28 cm

6. starting time =10.15 P.M.- 6 hours

=4.15 P.M.

7. volume of the cube=1000 cu cm

=10 cm×10cm×10cm

edge of the cube =10 cm

Answer 2

Step-by-step explanation:

3. perimeter = 4×side

=(4×40)cm

=160cm

4. 1 hr= 60 mins

now 888÷60

14 hrs 40 mins
