Which is true about the volume or surface area of these prisms?

Mariana [72]

Let us find the Surface area and Volume of both Prisms A and B to conclude which is greater.

Consider Prism A :

$\bigstar$ Given Length of Prism A is 3 m

$\bigstar$ Given Width of Prism A is 2 m

$\bigstar$ Given Height of Prism A is 10 m

We know that :

$\bigstar$ Surface Area of a Rectangular Prism is given by : 2[lw + wh + lh]

$:\implies$ Surface area of Prism A : 2[(3)(2) + (2)(10) + (3)(10)]

$:\implies$ Surface area of Prism A : 2[6 + 20 + 30]

$:\implies$ Surface area of Prism A : 2[56]

$:\implies$ Surface area of Prism A : 112 m²

We know that :

$\bigstar$ Volume of a Rectangular Prism is given by : L x W x H

$:\implies$ Volume of Prism A : [3 x 2 x 10]

$:\implies$ Volume of Prism A : 60 m³

-----------------------------------------------------------------------------

Consider Prism B :

$\bigstar$ Given Length of Prism B is 2 m

$\bigstar$ Given Width of Prism B is 6 m

$\bigstar$ Given Height of Prism B is 5 m

We know that :

$\bigstar$ Surface Area of a Rectangular Prism is given by : 2[lw + wh + lh]

$:\implies$ Surface area of Prism B : 2[(2)(6) + (6)(5) + (2)(5)]

$:\implies$ Surface area of Prism B : 2[12 + 30 + 10]

$:\implies$ Surface area of Prism B : 2[52]

$:\implies$ Surface area of Prism B : 104 m²

We know that :

$\bigstar$ Volume of a Rectangular Prism is given by : L x W x H

$:\implies$ Volume of Prism B : [2 x 6 x 5]

$:\implies$ Volume of Prism B : 60 m³

We can notice that Volumes of both Prism A and B are Equal, But the Surface Areas are not.

$\bigstar$ Surface Area of Prism A is 112 m²

$\bigstar$ Surface Area of Prism B is 104 m²

<u>Answer</u> : Surface Area of Prism A > Surface Area of Prism B
