Question

HELP THIS FAST PLS ( MY MATH )

Answer 1

Answer:

543cm²

Step-by-step explanation:

Divide the figure into cube and cuboid

Then the new dimensions will be

Cube :-

Length = 8cm

Cuboid :-

Length = 4 cm

Breadth = 4cm

Height = 8cm

TSA of Cube = 6l²(where l is the length of the cube)

=> TSA of Cube = 6(8)² = 384cm²

TSA of the cuboid = 2(lb+bh+hl)

here l = Length of the cuboid

b = Breadth of the cuboid

h = Height of the cuboid

=> TSA of the cuboid = 2[4(4)+4(8)+8(4)] = 160cm²

Total Surface area of the figure = TSA of Cube + TSA of Cuboid

∴ Total Surface area of the figure = 383+160 = 543cm²

Hope it Helps you !
