7 * 7 * 7 = 343 cubic centimetres (cc).
It is: 35/5 = 7cm
The rectangle is 23cm x 16cmHalf the perimeter is 78 / 2= 39cm (which is one side and one end).39 - 7 = 32cm32 / 2 = 16cm (one end)16 + 7 = 23cm (one side)Proof:(23 + 16) x 2 = 78cm the perimeter.
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
7cm
about 7cm long
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.
To find the area of a rectangle, you multiply the length by the width. In this case, the width is 7cm and the length is 9cm. So, the area would be 7cm x 9cm = 63 square centimeters.
16X7 CM.
What about it? What is the question?

Find the volume of a cuboid of length 7cm breath 5cm and height 6cm
The width is 10.5 cm.
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^
