Surface area = 2*(3*4 + 4*5 + 5*3) = 2*(12 + 20 + 15) = 2*47 = 94 sq ft.
2 x (3 x 3) + 4 x (3 x 4) = 2 x (9) + 4 x (12) = 18 + 48 = 66 square feet==> IF the box is sealed, i.e. the top is closed, so there are six sides to it.
(2 x 3 + 2 x 3 + 3 x 3) times 2 ie (6 + 6 + 9) x 2 = 42ft2

By using the equation 2B+Ph. B=2x3=6ft P=2+2+3+3=10ft h=4ft So, 2(6)+(10)(4)=52 square feet
No. If you want the area of a single surface of a box, simply multiply the height by the width of the surface of interest.

-- the space inside a cube (box) that's 4ft 1.5inch on every side -- the space inside a spherical balloon that's 5ft 1.4inch in diameter (across)

You multiply length X width X height in inches divided by 231. 231 is your magic number that makes the formula work, because their is 231 cubic inches in a gallon. To find the gallons of a box that is 2ft x 4ft x 3ft You would convert your numbers to inches then multiply. 24in x 48in x 36in =41,472 divided by 231 = 179.5 gallons,
A box is not any kind of surface because a box is a 3-dimensional object whereas a surface is 2 dimensional.
A cubic yard is: volume defined by a cube that is 3ft x 3ft x 3ft; i.e. 3ft high x 3ft wide x 3ft deep. For example: a box 3x3x3 feet filled with gravel is one cubic yard since a yard=3 feet.
It depends on the diameter and depth of the pool. It should say on the box.
to calculate the area of the front surface of a box you should
2ft by 2ft by 5ft is a possibility
