Answer 1

Answer:

320cm³

Step-by-step explanation:

to find the area of the rectangular prism we can use the formula V= LWH

6×8×5=240 cm³

to find the area of the triangular prism we use the formula V=1/2LWH

4×8×5×1/2=80cm³

240+80=320

Answer 2

Answer:

320cm³

Step-by-step explanation:

First, find the area of the triangle.

a=hb/2 (area = height * base / 2)

area = 4*8/2=16

Then, find the area of the rectangle.

a=wl (area = width * length)

area = 6*8=48

Then, you add the two totals and multiply the width (5cm).

16+48=64

64*5=320
