Volume of cuboid = l*b*h

= 3×5 × 7 = 105 m³

surface area of cuboid = 2(lb + bh + hl )

= 2(3 ×5 + 5×7 + 7×3 )

= 142 cm²

Hey Chika ❤

Check your answer in the attachment-

Given,
l = 3m
b = 5m
h = 7m

Formula for TSA,
$= 2(lb + bh + lh)sq.units$

and, formula for Volume,
$(l \times b \times h)cu \: units$

Hope it helps ✔
