Question

The side of the base of a dice is $5.5$ mm. Find the surface area of a dice whose edges are squares.

• A. $181.5{mm}^2$
• B. $90.21{mm}^2$
• C. $180.2{mm}^2$
• D. $120.4{mm}^2$

Answer 1

Answer: (A)

$181.5{mm}^2$

Given, side of base $=5.5$ mm

Total surface area of a cube $=$ $6\times$ side${}^2$
$=6\times 5.5\times 5.5$
$=181.5{mm}^2$
