Darren is painting a wooden block as part of his art project The block is a rectangular prism that is 12cm long by 9 cm wide by

Ksenya-84 [330]

Answer:

<h3>The surface area in square meters that Darren has to paint is $426cm^2$ </h3><h3>∴ $A=426cm^2$ </h3>

Step-by-step explanation:

Given that Darren is painting a wooden block is a rectangular prism

Its length is 12 cm ,width is 9 cm and height is 5 cm

<h3>To find the surface area in square meters that Darren has to paint :</h3>

Let l be the length, w be the width and h be the height

Then l=12 cm , w=9 cm and h=5 cm

The formula for the Surface area is

A=2(lw+wh+hl) square units

Substitute the values in formula we get,

A=2(12(9)+9(5)+5(12))

=2(108+45+60)

=2(213)

=426

<h3>∴ $A=426cm^2$ </h3><h3>∴ the surface area in square meters that Darren has to paint is $426cm^2$ </h3>
