That is 20 centimeters tall, we see that the height of Then we have two more sides,Ĭuz this box has six sides, We have this side panel See it right now, so that's gonna be another 30. Well, the bottom of theīox is gonna have the exact same area, we just can't So that's the top of theīox, 30 square centimeters. Gonna be three centimeters times 10 centimeters, which It's three centimeters deepĪnd it's 10 centimeters wide. The top of the box, we see theīox is three centimeters deep so this right over here Now let's figure out theĪrea of the top of the box. And so let's write anotherĢ00 square centimeters for the back of the box. Now we also know there'sĪnother side that has the exact same area as theįront of the box, and that's the back of the box. 200 centimeters, or 200 squareĬentimeters, I should say. Times 10 centimeters, and that's going to Out its area we can just multiply 20 centimeters Is 20 centimeters tall and 10 centimeters wide. Sides that we can't see are and how they might relate, and See, and then think about what the surface area of the The first way is, well let'sįigure out the surface area of the sides that we can And there's a couple of ways to tackle it. If all the edges of a rectangular prism are equal, then the surface area of the prism will be 6 times the area of the face.We can figure out the surface area of this cereal box.If all the vertices of a rectangular prism are the same as ‘l’, then the volume of the prism is given as ‘l3’.An oblique rectangular prism is stated as a prism in which faces are not perpendicular to one another.A rectangular prism with all sides the same is called a cube.The unit of measurement of the area of the rectangular prism is square units.The total surface area of a solid is the sum of the areas covered by all the faces or surfaces enclosing the object.Step 4: The units calculated are in square units. Step 3: Utilize the formula for the lateral surface area or the total surface area. Step 2: Once the dimensions are made the same, one can calculate the lateral surface area or the total surface area as per the condition given. Step 1: The given dimensions of the rectangular prism must be in same units if not then make same. The surface area of a rectangular prism can be found by using the following steps: How To Calculate the Surface Area of a Rectangular Prism Lateral surface area of a rectangular prism= 2(l+b) h The formula for the lateral surface area of a rectangular prism is, This does not include the area of the bases. The lateral surface area of a rectangular prism can be calculated by finding the sum of all the lateral faces of the prism. Lateral Surface Area of a Rectangular Prism Total surface area of a rectangular prism = 2(lb+bh+hl) The formula for the surface area of a rectangular prism is, The total surface area of a rectangular prism can be found by calculating the total area of all its six faces. Total Surface Area of a Rectangular Prism Lateral surface area of a rectangular prism.
