A solid cuboidal piece of iron measures 8 cm x 2 cm x 4 cm. Find its weight if1cm of iron weighs 12 grams.Ans: (768 gm)

Answer»

Volume of cuboid= l×b×h=2×4×8=62cm³1cm³=12 gram62cm³=62×12=744gram

Answer

744 gram

in the questions GIVEN ,

length of the cuboidal piece of iron equal to 8cm

breadth of the cuboidal piece of iron equal to 2cm.

height of the cuboidal piece of iron equal to 4 cm.

here we find the volume of cuboid = l × b×h

using formula ,

v of cuboid = l × b × h

8 × 2 × 4

16 × 4

64 cm 3.

again ,

1 cm3 iron weight equal to 12 grams .

then ,

64 cm3 iron weight equal to 64 × 12 gm equal to 768 gram.

therefore total weight A solid cuboidal piece of iron equal to 768gram.

Volume of cuboid= l×b×h=2×4×8=64cm³1cm³=12 gram62cm³=64×12=768gram

768 g is the right answer

the answer of the following question is 8×2×4 =64cm64×12=744gram

sorry the answer of the following question is 768

VOLUME OF CUBOID=L×B×H=(8×2×4)CM^3=64 cm^3WEIGHT OF 1 cm^3=12 gTHERE FOR WEIGHT OF 64 cm^3=12×64 g=768 grams .BEST ANSWER

volume of cuboid = L×b×hthen - 2×4×8= 64cm³1cm³ = 12 gram1cm³ =12gram62cm³=64 ×12 =768 Gram
