The surface area is 2*(8*11 + 11*3 + 3*8) square inches = 2*(88 + 33 + 24) sq inches = 290 square inches.
Multiply by 144, so: 2 square feet = 288 square inches
One square foot is 12 inches by 12 inches, = 144 square inches. Therefore 2 square feet is 2 x 144 = I'll leave you to do the math.
You can't convert that. You can convert feet to inches, or square feet to square inches.
288 square inches is equal to 2 square feet.
capacity of a box 5 inches square and 2 inches deep = 5 X 5 X 2 =50 inches ^ 3
To get the square inches in the box you need to multiply the length times width so a 2 inch by 4 inch box is 2x4= 8 square inches
Bottom = 119 square inches Top = 119 square inches 2 sides = 35 square inches each other 2 sides = 85 square inches each Total = 478 square inches of cardboard to build the box.
552 square inches.
52 square inches for each layer, minimum with no overlap anywhere.
To calculate the square inches of the surface area of a box the formula is 2*w*h + 2*l*h + 2*w*l. In this equation w stands for width, l for length, and h represents height.
Surface area of box: (2*6*4)+(2*6*2)+(2*4*2) = 88 square inches of gift wrap will be needed
Multiply 5 x 3 x2=30 inches. I don't agree, 5inX3inX2in=30 CUBIC inches and is the volume of the box. Square inches is a measure of area and the question is meaningless unless you are asking for the surface area of the box or a side of the box.
A foot is measured in a strait line, its a linear measurement of 12 inches.. A square foot is 12^2, or 144 square inches, it a box with 4, 12" sides.
2 inches by 120 inches = 240 square inches = 1 2/3 square feet
Yes because 1 foot = 12 inchesA square with an area of 1 square foot is 1 foot (long) by 1 foot (wide). Since a foot is 12 inches, the square area would be 12 inches long by 12 inches wide. If we filled the whole 12 inch by 12 inch box with little 1 inch by 1 inch boxes, we would have 144 little 1 square inch boxes.We can also multiple:12 inches x 12 inches = 144 inchesinches or 144 inches squared or 144 square inches.It does not have to be the shape of a square. if we arranged the 144 square inches in a box 6 inches by 24 inches (6 x 24 = 144) or a box 8 inches by 18 inches (8 x 18 = 144 or 2 inches by 72 inches (2 x 72 = 144) or even line of 1 inches by 144 inches (1 x 144 =144), they all are 144 square inches or 1 square foot. Even 1/2 inch by 288 inches or 1/4 inch by 576 inches has an area of 1 square foot.
Total surface = 2 lw + 2 lh + 2 hw = 386 L = 15 and W = 4 so we have 120 + 30h + 8h = 386 ie 38h = 266 so h = 7 inches
