Question

What is the surface area of the prism?

Answer 1

• Surface Area = 520 m² ( Option C is correct )

Explanation:

In this question we are given a rectangular prism which having :

• Length = 10 m

• Width = 8 m

• Height = 10 m

And we are asking to find the surface area of prism . We know that ,

`\blue{ \underline{ \boxed{ \sf{Surface \: Area_((Rectangular \: Prism)) =2(lw + wh + hl )}}}}`

Where ,

• l = Length of prism

• w = Width of prism

• h = Height of prism

Solution : -

Now solving by substituting value of length, width and height in the formula . So ,

`\longmapsto \quad \: 2( (10 * 8 )+ (8 * 10) + (10 * 10))`

`\longmapsto \quad \:2(80 + 80 + 100)`

`\longmapsto \quad \:2(160 + 100)`

`\longmapsto \quad \:2(260)`

`\longmapsto \quad \: \underline{\boxed{\frak{520 \: m {}^(2) }}}`✦

• Henceforth, surface area of given prism is 520 square metres which means option C is the correct answer .

Answer 2

520 m²

Here given:

length: 10 m
width: 8 m
height: 10 m

surface area of rectangular prism:

2(lw+hw+hl)

2(10*8+10*8+10*10)

2(80+80+100)

2(260)

520 m²
