What is the surface area of the composite solid? A rectangular prism has a length of 15 meters, width of 10 meters, and height of 25 meters. A triangular prism has a triangular base with a base of 6 meters and height of 8 meters. The prism has a height of 15 meters. 1,508 m2 1,658 m2 1,808 m2 1,958 m2

Surface area of rectangular prism = 1550m²

Surface area of triangular prism = 498m²

Step-by-step explanation:

The surface area of a rectangular prism is given by the formula

A= 2(wl+hl+hw)

Where A = surface area

w= width

l= length

h=height

Given that the rectangular prism has a length of 15 meters, width of 10 meters, and height of 25 meters.

A= 2(10×15+25×15+25×10)

A=2(150+375+250)

A=2(775)

A=1550 square meters

Surface area of triangular prism = base of triangle x height of triangle + (length of rectangle x width of rectangle) x 3

Since we are not given length and width of the triangular prism, we could assume the triangular prism has same length and width with the rectangular prism given that it is a composite shape(more than one solid in one)

Given triangular base with a base of 6 meters and height of 8 meters.

Surface area of triangular prism= 6×8+(10×15)×3

=48+150×3

=48+450

= 498 square meters

take it another

dude thats to long figure it
