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.
