Answer:

First rectangular solid and second Rectangular solid

1. Bases are in the form of square having same dimensions

2. Height of first rectangular solid=2 ×Height of second rectangular solid

The true statements are

A) The bases are congruent.→The meaning of term congruent is that , the two bases are in the shape of square having same dimensions.

(B) No, The solids are not similar.as ratio of side lengths in not same in each case , because the ratio of heights of two solid is equal to .

(D) Volume of first solid = x *x*2 H=2 x²H

Volume of second solid = x*x*H=x²H

Ratio of volumes =2:1

So, option (D) is true.

(E) Surface area of first solid =2[x*x+x*2 H+2 H*x]

=2[x²+4 H*x]=2 *x*[x+4* H]

Surface area of second solid = 2[x*x+x* H+ H*x]=2[x²+2 H*x]=2* x*[x+ 2*H]

Option A, D, E are correct about two solids.

What is the difference between the areas of a circular table with diameter 6 ft and a circular table with diameter 8 ft? Round y
MrMuchimi

If the diameter is given in a problem, area is computed as

A = (π/4) × D<span>2   where </span><span>π is equal to 3.14</span>

<span>If D (diameter)  of one circular table is 6 ft its  Area is 28 sq ft.</span>

If D of another circular is 8 ft its Area is 50 sq ft.

<span>The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.</span>
