Answer:
42 cm²
Explanation:
let :
length (l) = 3cm
breadth (b) = 2cm
height (h) = 3cm
formula to find the total surface area is:
2(l×b) + 2(l×h) + 2(b×h)
= 2(3×2) + 2(3×3) + 2(2×3)
= 2×6 + 2×9 + 2×6
= 12 + 18 + 12
= 42
in the figure we needed to find the area and the unit is in cm that's why the unit will be "cm²".
hence, the total surface area is 42cm².
