Unfortunately Professor C knows nothing whatsoever about mathematics, or else, ChefDepot.com is a rubbsih site.
31cm x 28cm x 7 cm is a 3-dimensional measure of volume whereas inches are a measure of distance or length. The two measure different things and it makes no sense to try to convert from one to the other.
7 cm(7cm x 7 cm x 7cm) = 343 cm3
48 cubic inches
Number of inches in 1 foot= 12 so, number of inches in x feet= 12*x
12 x 8 x 5 = 480 cubic inches
7.87in x 4.72in x 2.75in
Area= length x width. Therefore, Area= 7cm x 4cm=28cm squared.
It is 343 cubic cm
area= 7cm x 7cm = 49cm^2
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
Volume = 7cm x 7cm x 7cm = 343cm3 (343 cubic centimeters)
The radius is squared and timed by pi (3.14) 28cm x 28cm x 3.14 = 2461.76cm2
The circumference of a circle with radius measuring 28cm is about 175.9cm (C = r x 2 x Pi).
what is the perimeter of a rectangle that's 10cm x 7cm
10cm x 7cm x 12cm =840 square cm3
The volume of the tank is 51cm x 25cm x 31cm = 39525cm3 1 litre = 1000cm3 ⇒ divide 39525cm3 by 1000 convert to litres ⇒ 39.525 litres.
