2015年12月29日 · S = 2lw + 2lh + 2wh If we consider the structure of a box with length l, width w, and height h, we may note that it is formed from six rectangular faces. The bottom and top faces are rectangles with sides of length l and w. Two of the side faces have side lengths l and h. And the remaining two side faces have side lengths w and h. As the area of a rectangle is the …

2017年4月29日 · What is the volume and surface area of a tissue box with L= 9.25 W= 4.75 H= 3? Algebra Quadratic Equations and Functions Linear, Exponential, and Quadratic Models 1 Answer

The surface area of an open-top box with length L , width W , and height H can be found using the formula: A = 2 L H + 2 W H + L W Find the surface area of an open-top box with length 4 cm, width 3 cm, and height 8 cm.

Question: b) What is the surface area of the box where the length is four times the width. (see diagram)? Your answer will be in terms of both x and y. c) A rectangular box with a volume of 50 cubic meters where the length is four times the width. Express the surface area of the box as a function of the length of a side of the base, x.

Minimum-surface-area box Of all boxes with a square base and a volume of 100 m^3, which one has the minimum surface area? (Give its dimensions.) Maximum-volume box Suppose an airline policy stales that all baggage must be box-shaped with a sum of length, width, and height not exceeding 108 in.

2018年2月12日 · See below. Let's do a) first. We can predict, by the box, that the ratio will be 60/"cm" The formula for the surface area of a cube is 6s^2, where s is the side length. The volume of a cube is s^3. For 0.1cm, the surface area is 6*0.1^2 6*0.01 0.06cm^2 The volume is 0.1^3 0.001cm^3 The ratio is 0.06:0.001, which is equal to 60/"cm". Now for b). We can predict the …

Minimum-surface-area box Of all boxes with a square base and a volume of 8 m3, which one has the minimum surface area? (Give its dimensions.) 20. Maximum-volume box Suppose an airline policy states that all baggage must be box-shaped with a sum of length, width, and height not exceeding 108 in. What are the dimensions and volume of a square ...

2015年4月15日 · The Volume of a box with a square base x by x cm and height h cm is V=x^2h The amount of material used is directly proportional to the surface area, so we will minimize the amount of material by minimizing the surface area. The surface area of the box described is A=x^2 +4xh We need A as a function of x alone, so we'll use the fact that V=x^2h ...

2017年5月29日 · The surface area is 126. There are three different types of rectangular surfaces in each rectangular box. Overall surface area: 2*(6*5+3*5+3*6) =2*63 =126

b) What is the surface area of the box where the length is four times the width. (see diagram)? Your answer will be in terms of both x and y. c) A rectangular box with a volume of 50 cubic meters where the length is four times the width. Express the surface area of the box as a function of the length of a side of the base, x.
