Find the area of an equilateral triangle with altitude h cm?
The altitude of an equilateral triangle bisects the base. So, if the sides of the triangle were l cm, the altitude forms a right angled triangle with sides h, l/2 and hypotenuse l cm. Then, by Pythagoras, h2 = 3l2 / 4 so that h = l*sqrt(3)/2 and then area = l*h/2 = l*[l*sqrt(3)/2]/2 =l2*sqrt(3)/4
What is the length if area 100 square cm and perimeter 40 cm?
If P = 40 then L + W = 20. The only combination which gives A = 100 is where L and W are both 10, ie the figure is a square of side 10 cm.
If L equals 8 cm W equals 5 cm and H equals 4 cm what is the volume of the rectangular prism?
160cm3.
If L equals 15 cm W equals 9 cm and H equals 21 cm what is the surface area of the rectangular box?
1,278
What is the heght of a container that has a volume of a container that is 40 centimeters3 and has a length of 4 centimeters and a width of 2centimeters?
Volume = H x L x W 40 = H x 4 x 2 40 = H x 8 40/8 = (H x 8)/8 5 = H
The volume of a container is 40 cm3. It has a length of 4 cm a width of 2 cm. What is the height of the container?
To find the height of the container, you can use the formula for volume of a rectangular prism, which is given by V = l * w * h. Since the volume is 40 cm3, the length is 4 cm and the width is 2 cm, you can rearrange the formula to solve for height: h = V / (l * w) = 40 / (4 * 2) = 40 / 8 = 5 cm. Thus, the height of the container is 5 cm.
How do I find the width of a rectangle if I know its length and its perimeter?
To find the width of a rectangle, multiply the lenght by 2 and subtract it from the perimeter. Once this is done you are left with the two width sides of the rectangle. To find the width divide this number by 2 and you have your answer. For exaple: P= 120 cm L= 40 cm L* 2 = 80 120 - 80 = 40 40/2 = 20 W=20

160cm3.
If a rectangle has a length of 15 cm and a width of 5 cm what is the perimeter?
40 cm Perimeter = 2 L + 2W = 30 + 10
If L equals 15 cm W equals 9 cm and H equals 21 cm what is the surface area of the rectangular box?

What are some examples of rectangles with an area of 40cm?
A rectangle cannot have an area of 40 cm since the units for area are cm2. The following are some examples of rectangles with an area of 40 cm2: 10cm * 4 cm 1 000 cm * 0.04 cm 10*sqrt(2) cm * 2*sqrt(2) cm 10*pi cm x 4/pi cm Basically, take any number, L cm, as length and let 40/L cm be the breadth.
What is this L in Roman Numerals?
XL is 40, L is 50, LX is 60, LXX is 70, LXXX is 80
How many cubic feet is there in a 40 foot high cube container?
l*w*h = 40*40*40 = ft^3
What is the area of a right triangle that has legs 7 cm and 4 cm long?
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
