Multiply the width by the length.
e.g. you have a square that is 6 by 6 cm. 6x6 is 36, so the answer is 36cm squared.
Formula for finding the surface area of a sphere = 4*pi*radius2 in square units. Formula for finding the volume of a sphere = 4/3*pi*radius3 in cubic units. Or did you mean the formula for finding the area of a square? in which case it is Length*Height in square units.
what is the formula to finding the total surface area of a rhomboid?!
Total surface area in square units = (pi*radius*slant length)+(pi*radius squared)
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
the formula depends on the shape of the object
length2
length2
S=6e2
archimedes
the formula is lengh times width
