Question

Please answer for both lateral and total :)

Answer 1

The formula for lateral is S=Ph. P is perimeter, and h is height. For perimeter you have to add 20+25+15=60 The height is 30. Multiply 60x30 which gets you 1,800. That’s the lateral.

Answer 2

lateral= perimeter of base x height = 20 x 15 = 300cm^3

total= 20 x 15= 300 / 2 = 150. 20 x 30= 600. 15 x 30= 450. 25 x 30 = 750. 15 x 20= 300 = 2250
