Hi,
Shape of a rectangular solid is
cuboid,
Dimensions of the cubiod is
Length = l = 1.05 m
l = 1.05 × 100 cm = 105 cm
Breadth = b = 70 cm
Height = h = 1.5 cm
Volume of the solid = lbh
V = 105 cm × 70cm × 1.5 cm
V = 11025 cm³
According to the problem given,
1 cm³ iron weighs 8 grams
11025 cm³ iron weighs = 8 ×11025 gm
= 88200grams
= 88200/1000kg
=88.2kgs
Therefore,
Solid weighs 88.2 kg
