Question

Find the total surface area of a cuboid whose length, breadth and height are 9 m, 7 m and 4 m.​

Answer 1

Answer:

$l = 9 \: b = 7 \: h = 4 \\ sa = 2(lh + bh + lb) \\ = 2(36 + 28 + 63) \\ = 2 \times 127 \\ = 254 {cm}^{2} \\ thank \: u$

Answer 2

Length of a cuboid (l)= 9m

Breadth of a cuboid (b)= 7m

Height of a cuboid (h)= 4m

Total surface area of cuboid =2(lb+bh+hl)

=2(9×7+7×4+4×9)

=2(63+28+36)

=2(127)

=254 m²
