to get an average you total the digits. 20+3+23=46
Then divide by the number of digits, in this case 3
46/3 = 15 1/3
20cm
120 cm. If you multiply 4 cm times 3cm times 10 cm you will get= 120cm. Volume formula: l*w*h
Total area of board = 20cm*30cm = 600 cm2 Since 4 divides 20, there is no problem of left over strips. Area of each card = 4cm*3cm = 12 cm2 Number of cards = 600/12 = 50
20cm
Yes: 23cm = 230mm
0.23m = 23cm
You measure the sides of the shape you are finding the perimetre of and then add together the measurements. Then you have your answer. eg: 8cm x 7cm x 3cm x 5cm 8+7+3+5=23 answer is 23cm
They are usually 20cm in length (8 inches) The biggest one recorded is 23cm in length (9 inches)
About 20cm (200mm)
The circumference of a 23cm diameter circle is 72.3cm
volume 20cm 30cm 20cm
You multiply centimeters by 0.01 to get meters: 23cm = 23 x 0.01 = 0.23m
