Assuming that you mean cuboid, length and width, the answer is 13,824 square units.
To find the volume, multiply by the height x length x width. 7 x 5 x 21 = 735
Volume = L*W*H = 1.10cm*2.0cm*1.10cm (interesting that length < width!) = 2.42 cm3 Density = Mass/Vol = 10.0/2.42 = 4.13 grams per cm3
area - width = length
A triangle.
The lateral area of a cylinder whose diameter is 4cm and whose height is three times the radius equals approximately 75.4cm2

Draw the circle O, and the chord AB. From the center, draw the radius OC which passes though the midpoint, D, of AB. Since the radius OC bisects the chord AB, it is perpendicular to AB. So that CD is the required height, whose length equals to the difference of the length of the radius OC and the length of its part OD. Draw the radius OA and OB. So that OD is the median and the height of the isosceles triangle AOB, whose length equals to √(r2 - AB2/4) (by the Pythagorean theorem). Thus, the length of CD equals to r - √(r2 - AB2/4).
Volume = L*W*H = 1.10cm*2.0cm*1.10cm (interesting that length < width!) = 2.42 cm3 Density = Mass/Vol = 10.0/2.42 = 4.13 grams per cm3

The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
area - width = length
