What is the area of a triangular prism if the height is W inches the length W inches and the base W inches?
The answer depends on what sort of triangle: right angled, equilateral, isosceles or scalene.
What is the perimeter of a rectangle whose length is 2.5 greater than its width with an area of 37.5 square inches show work?
Suppose width = W inches. Then length, L = W + 2.5 inches. Area = L*W = (W + 2.5)*W which is 37.5 sq inches. Therefore W2 + 2.5W - 37.5 = 0 Multiplying by 2, to get rid of the fraction, 2W2 + 5W - 75 = 0 (2W +15)(W - 5) = 0 So W = -73.5 or W = 5 Since W is a length, it cannot be negative, so W = 5 inches Then L = W + 2.5 = 7.5 inches Therefore, the perimeter is 2*(L+W) = 2*(7.5 + 5) = 2*12.5 = 25 inches.
What is the height of a 6 inches wide 4 inches long prism if the surface area is 308 square inches?
Total surface area = 2*(H*L + L*W + W*H) 308 = 2*(6*4 + 4*W + W*6) that is 154 = 24 + 4W + 6W or 130 = 10 W so that W = 13 inches.
How many gallons is a tank 72 inches long by 24 inches deep by 24 inches tall?
1 gallon = 231 cubic inches. Multiply L X W X H (in inches) to get cubic inches, then divide by 231 to get gallons. 179.53 gallons
How many quarts are there in a container H 10.5 W 7.75 and L 12.25 inches?
10.5*7.75*12.25 = 996.84375 cubic inches. There are roughly 61 cubic inches in a litre, so you have 16.335 litres.
If the area of a rectangle is 40 square inches and the length is 6 inches more than the width what is the length and the width of the rectangle?
(6 + w) = length w = width (6 + w)(w) = 40 square inches w squared + 6w = 40 w = 4 inches and the length must be equal to 10 inches
The perimeter of a rectangle is 236 inches The length exceeds the width by 64 inches What is the length and width?
P = 2(L + W) = 236 L + W = 118 W + 64 + W = 118 (since L = W + 64) 2W = 54 W = 27 inches and then L = W + 64 = 91 inches
The perimeter of a rectangle is 32 inches Its length is 10 inches What is its width?
32 = L + W + L + W 32 = 10 + W + 10 + W 12 = W + W 6 = W
A magazine is 11 inches long and 8 inches wide what is the magazine's perimeter?
38 inches = perimeter 2*(w+l); 88 sq inches = Area (w*l)
The length in inches of a box is 3 inches less than twice its width in inches. Find the answer that gives the length l inches in terms of the width w inches of the box?
l = 2*w - 3
What size in inches is a Fat Quarter?
Approximately 18 inches by 22 inches.
How do you find total inches using L x W x H?
If you multiply L x W x H for a rectangular block if L, W, and H are in inches, you get a volume, in cubic inches, or in3.
The length of a rectangle is 3 inches more than the width the area of the rectangle is 154 inches Find the width of the rectangle?
Assuming that the area given is actually in squareinches, this can be solved as follows: Call the width inches w. Then, from the problem statement, the length is w + 3 inches. The area of any rectangle is the product of its length and width, so that:w(w+3) = 154; or w2 + 3w - 154 = 0, or (w + 14)(w - 11) = 0. This positive value of w for which this equation is true is 11 inches.
How many square inches of cardboard are used to make a 12 inches by 8 inches by 4 inches shoe box?
Since a box would be hollow to leave room for the shoes, what you're really looking for here is surface area. The formula is 2( L x W) + 2( L x H) + 2( H x W). It doesn't matter which side you label as H, W or L just be consistent.
The length of a rectangle is 6 inches more than its width The perimeter of the rectangle is 24 inches What is the length of the rectangle?
P of rectangle = 2(L+W) where L=W+6 24 = 2(W+(W+6)) 12 = W+ W+ 6 6 = 2 W 3 = W The length (W+6) is 9, width (W) is 3.
Perimeter of a rectangle is 140 inches the length exceeds the width by 36 What is the length and the width?
Suppose width = Wthen length L = W + 36 therefore perimeter, P = 2*(L + W) = 2*(W + 36 + W) = 4W + 72 = 140 Therefore 4W = 68 => W = 17 inches and so L = 17 + 36 = 53 inches.
