Question

The total surface area in $m^2$ of a cuboid whose dimensions are 26 m, 14 m and 6.5 m is :

• A. 1248 $m^2$
• B. 1240 $m^2$
• C. 1548 $m^2$
• D. 1200 $m^2$

Answer 1

The correct option is A 1248 $m^2$

Total Surface Area of a Cuboid
= 2( l x b + b x h + h x l)
= 2((26 ×14) + (14 × 6.5) + (6.5 × 26))
= 2(364 + 91 + 169)
$=1248m^2$.
