It is 17*(5+5+5) = 17*15 = 255 square units.

The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.

The surface are of a right prism is equal to twice the area of its base plus the perimeter of the base multiplied with the height of the prism. The volume can be determined by multiplying the Area of the base by the height of the prism.

Type your answer hereThe surface area of a prism is square root of 3* a 2 /4 + 3*a*h where a is edge of equilateral triangle and h is height of prism

The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.

It is 17*(5+5+5) = 17*15 = 255 square units.

The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.

Lateral area of the prism excluding the two ends: (3*20)+(4*20)+(5*20) = 240 square units

It is not possible to answer the question. A right triangular prism has sides of only four different lengths : the 3 sides of the triangular cross-section and the length of the prism. There are 5 lengths in the question. Even if there were only four lengths in the question, it is necessary to know which the sides of the triangle are and which the length is.

Given the four variables: baseA, baseB, hypotenuse, height, the formula is: (baseA+baseB+hypotenuse)*height+baseA*baseB

The surface area of a right prism is the sum of the areas of all its faces. The formula for calculating the surface area of a right prism is 2 × (base area) + (lateral area), where the base area is the area of the base shape and the lateral area is the sum of the areas of the remaining faces. The lateral area can also be calculated by multiplying the perimeter of the base shape by the height of the prism.
