Since a rectangular box or tank has opposite sides which are equal, we calculate each unique side's area, then add them up together, and finally multiply by two to find the total surface area. To determine this, we use the formula for great-circle distance between points, and solve for the longitude difference $\Delta \lambda$.įor a sphere of radius $R$, divide every appearance of $a$ and $b$ by $R$, then multiply the result by $R^2$. The surface area formula for a rectangular box is 2 x (height x width + width x length + height x length), as seen in the figure below. Question 1: Find the area of the rectangle if the length is 7 cm and the width is 5 cm. The formula is: A L W where A is the area, L is the length, W is the width, and means. Step 2: L X L L 2, where L is the length of each side. To find the area of a rectangle, multiply the length by the width.

Prisms are solids with flat parallelogram sides and identical. Let's build our equation for surface area of a rectangular box starting with our cube formula: A 6a2 A 6 a 2 A 6(452) A 6 45 2 A 6(2,025) A 6 2,025 A 12,150 cm2 A 12,150 cm 2 As is your club's tradition, you will use the Permanent Records of the Club Elders to wrap the prized Cube Root Cube. Ball Surface Area Cone Surface Area Cube Surface Area Cylindrical Tank Surface Area Rectangular Tank Surface Area Capsule Surface Area Cap Surface Area. Assume we are working on a sphere of radius $1$, or consider the lengths in radians and the areas in steradians.Įxtend the sides of length $l$ until they meet. The surface area of a rectangular prism is the total area or region covered by its six faces.
