Which could be the area of the base of the triangular prism?     [Not drawn to scale]6 ft210 ft212 ft220 ft2
Alexus [3.1K]
For this case, the first thing we must observe is that the base of the prism is a triangle.
 The area of the triangle is given by:
 A = (1/2) * (b) * (h)

 Where,
 b: base of the triangle
 h: height of the triangle
 Substituting values we have:
 A = (1/2) * (4) * (3)

A = 6 ft ^ 2
 Answer:
 
The area of the base of the triangular prism could be:
 
A = 6 ft ^ 2

the right rectangular prism shown has a length of 8ft a width of 2ft and a height of 6ft the dimensions of the prism are doubled
Elan Coil [88]

Answer:

Part 1) The scale factor is 2

Part 2) The dimensions of the enlarged prism are

a.Length=(8)(2)=16 ft

b.Width=(2)(2)=4 ft

c.Height=(6)(2)=12 ft

Part 3) The surface area of the smaller rectangular prism is 152 ft^{2}

Step-by-step explanation:

we now that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

Part 1)

Find the scale factor

we know that

If the dimensions of the smaller prism are doubled , then the scale factor from the smaller rectangular prism to the larger rectangular prism is equal to 2

Part 2)

we know that

To find the dimensions of the enlarged figure, multiply the dimensions of the smaller prism by the scale factor

so

Length=(8)(2)=16 ft

Width=(2)(2)=4 ft

Height=(6)(2)=12 ft

Part 3) Find the surface area of the smaller rectangular prism

we know that

The surface area of the rectangular prism is equal to the area of its six rectangular faces

SA=2(8)(2)+2(2)(6)+2(8)(6)=152 ft^{2}
