It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
The base of a rectangular prism is a rectangle. The area of a rectangle is length times width.
The cross-section of a prism is the same - it is the same as the shape of the two parallel "bases"; this cross-section can be any shape, not necessarily a rectangle. Each side of a prism is rectangular, so knowing the formula for a rectangle will help you along to finding the surface area of the prism by helping you to calculate the area of the sides; however, you will still need to be able to calculate the area of the bases (unless it is given to you), for which knowing the area of a rectangle may not (usually will not) help.
Volume of a rectangular prism= LengthXWidthXHeight Area of a Rectangle= LengthXWidth Area of a Trapezoid= (Bottom+Top)/2)XHeight
If the base is a rectangle, use the formula for the area of a rectangle.
Area of a rectangular prism = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
if 3x4 is dimension of rectangle and 5 is the altitude, then, 49.035 sq. units is its surface area
Three: 1) The area of the cross-sectional rectangle end 2) The area of the rectangle joining the longer side of the cross-sectional rectangular ends 3) The area of the rectangle joining the shorter side of the cross-sectional rectangular ends Then the surface area of the rectangular prism is twice the sum of these three areas.

There is no rectangular prism below 8 8 19.
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
Volume of a rectangular prism= LengthXWidthXHeight Area of a Rectangle= LengthXWidth Area of a Trapezoid= (Bottom+Top)/2)XHeight
it is when you for example==== surface area = 2(6)(4) + 2(6)(3) + 2(4)(3) = 108 in. square surface area of a solid is the sum of the areas of the outside surfaces of a solid
If the base is a rectangle, use the formula for the area of a rectangle.
432 square units.
