Calculate the surface area of each prism to the nearest tenth of a centimetre. a) 12cm 1. 6 cm 175CT

Calculate The Surface Area Of Each Prism To The Nearest Tenth Of A Centimetre A 12cm 1 6 Cm 175CT class=

Answer :

Answer:

[tex]\text{ }A=736.4cm^2[/tex]

Explanation:

Here, we want to get the surface area of the given prism

Mathematically, we know that the surface area is:

[tex]\text{ A = 2(lb+lh+bh)}[/tex]

where l is the length, b is the breadth and h is the height of the prism

]

From the diagram shown, we have these values as 6 cm, 17.5 cm and 11.2 cm

Substituting these values into the formula, we have it that:

[tex]\begin{gathered} \text{ A = 2(6}\times17.5\text{ + 6}\times11.2\text{ + 17.5}\times11.2) \\ A\text{ = 2(105 + 67.2+196)} \\ A=736.4cm^2 \end{gathered}[/tex]
