Answer:

So Prism D has the greatest volume.

Step-by-step explanation:

Since volume of a triangular prism = A × h

where A = Area of base of prism

h = height

For prism (A) ⇒ Volume = ( 6 × 7 ) × 9

= 42 × 9 = 378m³

Prism (B) ⇒ Volume = ( 5 × 6 ) × 13

= 30 × 13 = 390m³

Prism (C) ⇒ Volume = ( 11 × 8 ) × 8

= 88 × 8 = 704m³

Prism (D) ⇒ Volume = ( 10 × 8 ) × 9

= 80 × 9 = 720m³

So prism D has the maximum volume.

Find the total surface area of these solids

12345 [234]

<h2>Step-by-step explanation:</h2><h3>We firstly find the surface area of only one face of the cube:</h3><h3>Sa=a²</h3><h3>Sa=1.2²cm</h3><h3>Sa=1.44cm²</h3>

<h2>Since the cube has 6 faces we multiply the surface area of one face(144cm²) with 6</h2>

Area(cube)=1.44cm²*6

=8.64cm²

<h2>Same thing with the prism but we have to find the area of one of his triangle face and rectangle face</h2>

S(triangle)=5mm*4mm*1/2

=10mm²

S(rectangle)=7mm*5mm=35mm²

<h2>The prism has 2 triangle faces and three rectangle faces so we multiply the area by those numbers and then we add those together to get the final area</h2>

S=10mm²*2+35mm²*3

S=20+105

S=125mm²
