Answer 1

Given :- A 56.8 kg concrete slab can be balanced by two concrete pillars, each weighing 41.3 kg. How many concrete pillars are needed to support slabs that weigh 681.6 kg ? Calculate the total weight of the slabs and the pillars. ?

Solution :-

we have given that, A 56.8 kg concrete slab can be balanced by two concrete pillars.

we can say that,

→ 56.8 kg concrete slab can be balanced by = 2 pillar.

So,

→ 1 kg concrete slab can be balanced by = (2/56.8) Pillars.

Than,

→ 681.6kg concrete slab can be balanced by = (2 * 681.6) / (56.8) = 24 Pillar. (Ans.)

Now, we have given that,

→ weight of 1 Pi|lar = 41.3 kg.

So,

→ weight of 24 Pillars = 41.3 * 24 = 991.2 kg.

Therefore,

→ Total weight of slab and the pillars = 681.6 + 991.2 = 1672.8 kg .(Ans.)
