What is the surface area of a rectangular prism if its 14 ft long 8 ft wide and 9 ft high?
2(9*8 + 9*14 + 8*14) = 620 square feet.
What is the surface area of a prism with a length of 15mm a height of 4 mm and a width of 3mm?
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
What is the surface area of a rectangular prism that is 6 inches long 8 inches wide and 2 inches high?
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.
What is the volume of a rectangular prism that is 5 centimeters wide 10 centimeters long and 4 centimeters high?
