Calculate the Total Surface Area of the Triangular Prism Shelf

Thandi is building a wooden triangular wall shelf at his home which is shaped like a prism. The triangular side has a base of 40 cm, a height of 30 cm and the other two sides each measure 50 cm. The shelf is 1 m long (100 cm).

40 cm 30 cm 50 cm 50 cm 100 cm
Given:
Base of triangle = 40 cm
Height of triangle = 30 cm
Two equal sides = 50 cm each
Prism length = 100 cm
Formula:
TSA = 2 × Triangle Area + 3 × Rectangles
Triangle = (1/2) × 40 × 30
Rectangles = 40×100 + 50×100 + 50×100
Find the total surface area of the shelf in cm².
