Question

The total surface area of a cuboid with dimensions of $26\times 14\times 6.5$ m respectively is _____ m${}^2$.

• A. 1248
• B. 1448
• C. 1000
• D. 2400

Answer 1

The correct option is A 1248

Given, Solid: Cuboid
Length, $l=26\text{m}$
Breadth, $b=14\text{m}$
Height, $h=6.5\text{m}$

Total Surface Area of Cuboid
$=2(lb+bh+hl)=2(26\times 14+14\times 6.5+6.5\times 26)=2(364+91+169)=1248{\text{m}}^2$
