13. a rectangular prism has the following dimensions. length: 8 cm width: 13 cm height: 10.5 cm if all the dimensions of the prism are doubled, what will be its new surface area? 1,298 cm2 4,192 cm2 2,596 cm2 4,368 cm2

Step-by-step explanation:

Given dimensions of rectangular prism :

length: 8 cm

width: 13 cm

height: 10.5 cm

If all the dimensions of the prism are doubled, then the new dimensions will be:

length: 16 cm

width: 26 cm

height: 21 cm

The surface area of rectangular prism is given by :-

Hence, its new surface area

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
