Surface area of a cuboid whose length, breadth and height are 10 cm, 8 cm and 8 cm is
A) 640 cm2
B) 224 cm2
C) 448 cm2
D) 288 cm2
Answered Feb 05, 2023
Correct option is (C) 448 cm2
Surface area of cuboid \(=2\,(lb+bh+hl)\)
\(=2\,(10\times8+8\times8+8\times10)\)
\(=2\,(80+64+80)\)
\(=2\times224=448\,cm^2\)
Correct option is C) 448 cm2
Correct Answer - `17.1cm^(2)`
Correct Answer - (i) `432 cm^(3), 180 cm^(2), 372 cm^(2)` (ii) `2366 m^(3), 520m^(2), 1248 m^(2)` (iii) `45 m^(3), 21 m^(2), 201 m^(2)` (iv) `36m^(3), 291 m^(2), 303 m^(2)`
Correct Answer - `269.5 cm^(3)`
Let l be the side of the cube and L, B, H be the dimensions of the cuboid Since l3 = 64 cm3 ∴ l = 4 cm Total surface area of cuboid is...
Correct option is (A) 3 cm Height of cuboid \(h=\frac V{lb}\) \(=\frac{60}{5\times4}\) = 3 cm
Correct option is (D) 16 Let \(l,b\;and\;h\) are length, breadth and height of the original cuboid. After increasing each dimension of cuboid by 4 times, length of formed cuboid \(=4\,l,\) breadth of formed cuboid = 4b and height of formed...
1. B) 405 cm3 2. C) 405 cm2 3. D) 8 4. D) 4 : 9
