Answer 1

Answer:

1750 cm²

Step-by-step explanation:

Given:

Dimensions of cardboard:

Length (l) = 25cm

Breadth (b) = 20cm

Height (h) = 15cm

To Find:

TSA of Box

Solution:

TSA of rectangle = 2(lb + bh + hl) unit²

∴ TSA of Card board = 2( 25×20 + 20×15 + 15×25) cm²

                                   = 2(500 + 300 + 375) cm²

                                   = 2(875) cm²

                                   = 1750 cm²

∴ The TSA of the cardboard box is 1750 cm²
