The Elephant Hawk-moth is a medium-sized hawk-moth, on the wing from May to July and active at dusk. It is commonly found in parks and gardens, as well as woodland edges, rough grassland and sand dunes.
3. Given the volume, length and width find the height, surface area, and diagonal of a rectangular prism. 1  V, l and w are known; find h, S and d. 2  h = V / lw. 3  S = 2(lw + lh + wh). 4  d = â(l 2 + w 2 + h 2).
The surface area of a prism = 2 area of base + perimeter of base H The actual formula used to find the surface area will depend on the shape of the base of the prism. For example: The 'Method' section below shows you how to use Maths Helper Plus to calculate surface areas and volumes of rectangular prisms.
