To calculate the area of the front surface of a box you would do what?
Measure the height and multiply it by the width.
Is the sound reflected back to the source from a concave shaped surface more or less than reflected from a flat surface?
Consider a sphere (a round ball) of radius r. The surface area is 4 PIr2, whereas the volume is (4/3)PIr3. So the surface-area-to-volume ratio of a sphere is (4 PIr2) / [(4/3)PIr3], which can be reduced to 3/r. As in the cube, the surface-area-to-volume ratio of 3/r holds true for all spheres. In the previous description, the symbol 'PI' is meant to represent Pi, or 3.1415 ... T Irregular Objects For irregular objects, such as a rectangular prism (a box) with different lengths in each dimension, the surface-area-to-volume ratio must be calculated for each shape. Consider a box with dimensions of l (length), w (width), and h (height). Like the cube, the box has six faces, but it is easier to consider it as three face pairs (front/back, left/right, and top/bottom). The surface area of both faces in a pair are the same (the front face has the same surface area as the back face). So the surface area of the box is: A = 2(l x w) + 2(w x h) + 2(l x h), or 2( (l x w) + (w x h) + (l x h) ). The volume is: V = l x w x h So the surface area to volume ratio (A/V) of a box is: 2( (l x w) + (w x h) + (w x h) ) / (l x w x h). The surface-area-to-volume ratio of a cylinder (like a soup can) is: ( (2 PI r2) + (2 PI r h) ) / (PI r2h) Where r is the radius of the circle on the top and bottom of the cylinder, h is the height of the cylinder, and. PI is Pi, or 3.1415 ... Unlike regular objects, such as the cube or sphere, no further simplification of the box's or cylinder's surface-area-to-volume ratio equation exists. The above appropriate equations must be applied to each box or cylinder separately.
Which exerts more pressure on the ground an empty cardboard box or the same piece of carboard after it has been flatened for recycling and why?
the empty cardboard box because pressure decreases with increase in area of surface. pressure = force / area. thus pressure is indirectly proportional to area...
Why is it easier to pull a box across a surface with an upward angle then push a box across a surface with a downward angle?
Push a box across a surface with a downward angle because gravity is helping.
A 2.7-kg box is released on a horizontal surface with an initial speed of 2.9 ms It moves on the surface with a deceleration of 0.27 ms2 Calculate the kinetic friction force on the box?
Net force = 20-12 = 8N Mass = 2 kg Using F = ma, we get required a = F/m = 8/2 = 4 m/s2
To calculate the area of the front surface of a box you?
multiply the length by the height
To calculate the area of the front surface of the front of a box?
If it's just the front surface of a box then it's simply a 2D shape, the area can be calculated by multiplying the length by the width. Answer will be in units squared.
To calculate the area of the front surface of a box you must do what?
multiply the height by the width
To calculate the area of the front surface of a box you would do what?
Measure the height and multiply it by the width.
How do you calculate the area of the front surface of the box?
You measure the sides, and multiply the top and side.
If you multiply the length by the height then divide by two can you calculate the area of the front surface of a box?
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.
How do you calculate the front of a box?
You cannot "calculate" the front of a box. You can calculate its dmensions, or its area but calculating it does not make sense. As for calculating its size or area, the answer will depend on what information you have and what you require.
To calculate the are of the front surface of a box you?
You multiply the length times the width of the surface.
How do you calculate the area of a front surface box?
height x length
What do you do to calculate the front surface of a box?
Because a box has 6 faces, the "front surface" is not detailed enough. If you are referring to the surface perpendicular to the ground and is facing you, then you simply multiply the height of the box by the edge of the base on the front surface.
Tocalculate the area of the front surfaceof a box?
The front surface of a box is a rectangle. If you only need the area of the front surface, then it doesn't even matter what it's part of. Multiply the width of the surface by its height. The answer is its area.
How do you calculate the total surface area of a box?
The surface area of each side of the box ( there should be six sides unless it doesn't have a top ) added together will give you the total surface area. The surface area of one side is calculated by multiplying the length and the width. The answer will be in square inches or square centimeters depending on what unit of measure you use.
