Answer:
[tex]\large\boxed{S.A.=368\ cm^2}[/tex]
Step-by-step explanation:
The formula of a surface area of a rectagular prism:
[tex]S.A.=2(lw+lh+wh)[/tex]
l - length
w - width
h - height
We have the dimensions 6cm × 14cm × 5cm. Substitute:
[tex]S.A.=2(6\cdot14+6\cdot5+14\cdot5)=2(84+30+70)=2(184)=368\ cm^2[/tex]
The surface area of the rectangular prism is 368 cm²
To calculate the surface area of the prism, we use the formula below.
Formula:
- As = 2(lw+lh+wh).............. Equation 1
Where:
- As = Surface area of the prism
- l = Lenght of the prism
- h = height of the prism
- w = width of the prism.
From the question,
Given:
- l = 6 cm
- w = 14 cm
- h = 5 cm
Substitute these values into equation 1
- As = 2[(6×14)+(14×5)+(6×5)]
- As = 2(84+70+30)
- As = 2(184)
- As = 368 cm²
Hence, The surface area of the rectangular prism is 368 cm².
