9x6=64 feet
Surface areas are measured in square units, such as square inches, square feet, square meters, etc. To determine the surface area, first ensure you have the length and width of the rectangle expressed in the same units (both in inches, both in feet, etc.), then multiply the length by the width: 2 feet x 3 feet = 6 square feet
54 square feet. A cube has 6 identical surfaces. A 3 ft cube has 6 surfaces each measuring 3ft x 3ft = 9 sq.ft. per surface. So 9 x 6 = 54 sq. ft. total surface area.
ok, so think about it. a cube has 6 sides. The surface area is the area of the surface of all 6 sides combined, so you divide the surface area by 6. This gives you the area of each square on each side. Then square root the answer because the area of a square is the side length squared. Now you have the edge length!
Surface area = 6*7.252 = 315.375 sq inches.
Surface area of box: (2*6*4)+(2*6*2)+(2*4*2) = 88 square inches of gift wrap will be needed
72 square feet
358 feet squared
Surface Area = ~636.17 ft2
The curved surface area of a cylinder whose height is 14 feet and radius is 6 feet is 527.79ft2
Surface area is 188.5 feet2
It is: 2(3*4)+2(3*6)+2(4*6) = 108 square feet
Volume is how much an object can store - like how much can you put inside a box. Surface area is the sum of the area of an objects surfaces - such as if you have a box, find the area of one side. Then you just multiply it by 6 (because a box have 6 faces) to get the total area of an object's surface.
The formula is 6s2 so 6(2.2)2 is equal to about 29 or 29.04 to be exact
It is: 2(3*2.5)+2(6*2.5)+2(3*6) = 81 square feet

Each face of the cube has an area of 36 square feet (6 x 6). With 6 faces, the area is 6 x 36 sq ft = 216 square ft
It is 180 square feet.
