Assuming a rectangular prism.
The surface area is 550 square inches.
2(9*8 + 9*14 + 8*14) = 620 square feet.
The surface area of a prism is twice the area of the end plus the area of all the sides. For a prism with a polygon cross-section the area of all the sides if given by the perimeter of the cross-section polygon multiplied by the length of the prism. Assuming you have a prism of cross-section that is a rectangle with sides 4 mm and 3 mm, and is 15 mm long (ie it is an oblong), its surface area is: → surface_area = 2 × (4 mm × 3 mm) + 2 × (4 mm + 3 mm) × 15 mm → surface area = 2 × 12 mm² + 14 mm × 15 mm = 234 mm²
To find the total surface area of a prism you add the lateral area and the areas of the two congruent bases. The formula is:Surface area = L.A. + 2B, where B is the area of the base.S.A. = L.A. + 2BSince the L.A. = 2(lh + hw) added to the area of the two bases, 2B = 2lw, another formula for the surface area can be S.A. =2(lh + hw + lw).By substituting the given values, l = 6 in, h = 2 in, and w = 8 in, in the surface area formula we have:S.A. = 2(lh + hw + lw)S.A. = 2[(6)(2) + (2)(8) + (6)(8)] = 2(12 + 16 + 48) = 2(76)S.A. = 152Thus, the surface area of the prism is 152 square inches.
A rectangular prism that is 5 centimeters wide, 10 centimeters long and 4 centimeters high has a volume of 200cm3
Surface area is 600 cm2
The cross section area times the height (or length depending on how you look at it). What is the area of the pentagon? how high/long is the prism?
Surface area of a rectangular prism = 2 x (length x width + width x height + height x length → surface area = 2 x (24 in x 4 in + 4 in x 5 in + 5 in x 24 in) = 472 sq in.
The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.

The surface area of a prism is twice the area of the end plus the area of all the sides. For a prism with a polygon cross-section the area of all the sides if given by the perimeter of the cross-section polygon multiplied by the length of the prism.

To find the total surface area of a prism you add the lateral area and the areas of the two congruent bases. The formula is:Surface area = L.A. + 2B, where B is the area of the base.S.A. = L.A. + 2BSince the L.A. = 2(lh + hw) added to the area of the two bases, 2B = 2lw, another formula for the surface area can be S.A. =2(lh + hw + lw).By substituting the given values, l = 6 in, h = 2 in, and w = 8 in, in the surface area formula we have:S.A. = 2(lh + hw + lw)S.A. = 2[(6)(2) + (2)(8) + (6)(8)] = 2(12 + 16 + 48) = 2(76)S.A. = 152Thus, the surface area of the prism is 152 square inches.
i think the area is 132in.--Another Answer:-It is: 2(2*5)+2(2*8)+2(8*5) = 132 square inches
You cannot find a unique solution because blocks of different shapes and volumes can still have the same surface area.You can find the dimensions of a cube with the given surface area; it is the largest volume of a rectangular prism for a given surface area.A cube has six equal square sides. Take the total surface area "At", divide this by 6 to get the area of one side "As":At / 6 = AsThe length Ls of one side of the cube is the square root of As .Ls = sqrt (As ) = sqrt (At / 6 )All the edges of a cube are of course the exact same length.Another solution is a very thin square prism (almost a sheet but with a finite thickness) with the top and bottom just slightly less than half the surface area; the remainder has to be spread out along the edge which can be arbitrarily narrow.Theoretically you can have a very long rectangular prism and so very large values for the length if the height and width are very small and still have the surface area set out in the problem.
