It is (2*L*W + 12*L + 12*W) cm2.
To calculate area, or cm2, the length and width must be multiplied. For example, a length of 2 cm and a width of 3 cm equals an area of 6 cm.
Area = length x width ⇒ width = Area ÷ length = 34 cm2 ÷ 9 cm = 37/9 cm ~= 3.78 cm
A line has no width nor depth, so it has no surface, thus its surface area is 0 cm2
50 cm2
L = 10W = 5H = 42 faces have area = 502 faces have area = 402 faces have area = 20Total surface area = 220 cm2
For a rectangle, length X width = area. Measure the length in cm. Measure the width in cm. Multiply the length X the width to get the area in cm2.

To calculate area, or cm2, the length and width must be multiplied. For example, a length of 2 cm and a width of 3 cm equals an area of 6 cm.
area=length*width width=area/length w=161/14 w=11.5
Area = length x width ⇒ width = Area ÷ length = 34 cm2 ÷ 9 cm = 37/9 cm ~= 3.78 cm
126 / 9 = 14cmRemember:Area = Length x WidthWhich can be written as...Length = Area / WidthOr...Width = Area / Length
A line has no width nor depth, so it has no surface, thus its surface area is 0 cm2

Width of rectangle: 50/10 = 5 cm
Height of side = square root of (625 cm2 + 196 cm2) = 28.65 cm Surface area of 4 sides = 4 x 28.65 cm x 14 cm = 1,604 cm2 Area of base = 196 cm2 Total surface area, including area of base, is 1,800 cm2
