weight of a metal block of sides 5 metre / 4 cm/3 cm find weight of block of same metal of size 15 cm by 18 cm / 3 cm

$\huge \underline \mathbf \blue{Solution ⤵}$

Given details are ,

Dimensions of metal block = 5cm × 4cm × 3cm

Weight of block = 1 kg

Volume of box = 5×4×3 = 60 cm³

Dimension of new block = 15cm × 8cm × 3cm

Volume of new box = 15 × 8 × 3 = 360 cm³
