Cuboid dimensions
Length (l) = 20 m
Height (h) = 8 m
Width (w) = 10 m
Length of the diagonal
= √(l^2)+ (w^2) + (h^2)
= √(400 + 64 + 100)
= √564
= 23.811 meters
Volume of cuboid
= l * w * h
= (20)(10)(8)
= 1600 cubic meters
Total surface area of cuboid
= 2 (lw + wh + lh)
= 2 (200 + 80 + 160)
= 2 (440)
= 800 square meters
Lateral surface area of cuboid
= 2 (lh + wh)
= 2 (160 + 80)
= 2 (240)
= 480 square meters
Hope it helps.
