Question

Find the total surface area of cuboid whose length = 5 cm breadth equal to 2.5 cm height equal 7 cm

Answer 1

heya mate here is your answer.....

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

2(5*2.5+2.5*7+7*5)

2(12.5+17.5+35)

2(65)

130cm²

hope this helps you......

Answer 2

Answer

$length = 5cm \\ breadth = 2.5cm \\ height = 7cm \\ \\ total \: surface \: area \: of \: \\ cuboid \: = 2 \times (lb + bh + hl) \\ \\ 2 \times (5 \times 2.5 + 2.5 \times 7 + 7 \times 5 \\ cm) \\ \\ 2 \times (12.5 + 17.5 + 35) \\ 2 \times 65 \\ 130 {cm}^{2}$
# A cuboid is a convex polyhedron.

# A cuboid have 6 faces.

#It have 12 number of edges.

# All angles are right angles.

# Simply , cuboid is made up of 6 rectangles.
