Question

triangular prism is 10 cm the side of the base is 3cm 4cm 5cm then TSA is​

Answer 1

Step-by-step explanation:

Given, sides of prism are 3 cm, 4 cm and 5 cm and height =10 cm

Let s be the semi-perimeter of the triangular base of the prism.

Then S = 3+4+5 / 2 = 6 cm

Therefore, the area of the prism

= √s(s−a)(s−b)(s−c)

=√6(6−3)(6−4)(6−5)

= √6×3×2×1

= √36 =6 sq. cm.

Then volume of the prism =area of base×height

= 6×10

= 60 cu.cm
