Mathematics
1 answer:
netineya [11]2 years ago
7 0

Answer:

<h3>Surface Area = 1,256 cm</h3>

<u>Solution:</u>

formula: Surface Area of a Sphere: 4π · r²

Surface area = 4π · r²

SA = 4(3.14) (10)²

SA =  (12.56)(100)

SA = 1,256

Cindy works at Jurassic Park and has been tasked to design a container in the shape of a rectangular prism for the incoming baby
svetoff [14.1K]

The amount Cindy should increase in each dimension of the scaled model is 12 m.  

<h3>What is a rectangular prism?</h3>

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

We have:

The scaled model of the container has dimensions 2m by 4m by 6m.

Volume of the scaled model = 2×4×6 = 48 cubic m

Let x be the amount by which each dimension is increased.

(2 + x)(4 + x)(6 + x) = 84(48)

\rm 48+44x+12x^2+x^3=4032

\rm x^3+12x^2+44x-3984=0

\rm x-12=0\quad \mathrm{or}\quad \:x^2+24x+332=0

The quadratic equation has no real solution so,

x = 12 m

Thus, the amount Cindy should increase in each dimension of the scaled model is 12 m.
