Question

Find the surface area of the prism 4cm 5cm 12cm 13cm

Answer 1

the answer would depend on where the numbers you gave us are on the pyramid. but here is the formula  to find the surface area of a prism; 
surface area= base x height + 2 x length x side + length x base
i will do the equation for you if you specify which numbers are the base, length, side, and height. or if you attach a photo.

Answer 2

Answer with explanation:

Surface area of any Prism = P H + 2 B

P= Perimeter of base

H= Height of prism

B= Base Area

As, prism is Right triangular Prism, having side lengths, 5 cm ,12 cm and 13 cm,and Height = 4 cm.

Perimeter of Base which is in the shape of triangle = 5 +12 +13=30 cm

Area of Right triangle, having Altitude and Base =5 cm and 12 cm

    $=\frac{1}{2} \times \text{base}\times \text{height}\\\\=\frac{1}{2} \times 5 \times 12\\\\=30 cm^2$

So, Surface Area of Prism = 30 × 4 +2 ×30

                           =120 +60

                           =180 cm²
